In 2006, RTHK broadcast a television film called Gay Lovers, which received criticism from social conservatives for "encouraging" people to become gay. In 2007, the Broadcasting Authority ruled that the RTHK-produced programme "Gay Lovers" was "unfair, partial and biased towards homosexuality, and having the effect of promoting the acceptance of homosexual marriage." On 5 May 2008 Justice Michael Hartmann overturned the ruling of the Broadcasting Authority that "Gay Lovers"'s discussion on same sex marriage was deemed to have breached broadcasting guidelines for not including anti-gay views.
^ For example, Virginia Prince used transgender to distinguish cross-dressers from transsexual people ("glbtq > social sciences >> Prince, Virginia Charles". glbtq.com. Archived from the original on 2015-02-11.), writing in Men Who Choose to Be Women (in Sexology, February 1969) that "I, at least, know the difference between sex and gender and have simply elected to change the latter and not the former."
Then, to complicate things further, I have learned a lot from my intersex, genderqueer and transgender friends. I now realize that I had been confusing gender with biological sex and that the two are not synonymous. Though in reality the difference between sex and gender is far more complicated, I find useful the expression, “Sex is between your legs; gender is between your ears.” In real people, sex and gender do not always correspond. I also learned that sex and gender each exist on a continuum; thus there are more than two sexes, and more than two genders. A male-bodied person can identify as a woman, or as a combination of man and woman; and a female-bodied person can identify as a man, or as a combination of man and woman. And some people’s bodies do not fit their cultures’ standards of male or female.
The Human Rights Campaign, the largest LGBT rights organization in the United States, states that "many same-sex couples want the right to legally marry because they are in love — many, in fact, have spent the last 10, 20 or 50 years with that person — and they want to honor their relationship in the greatest way our society has to offer, by making a public commitment to stand together in good times and bad, through all the joys and challenges family life brings."
Ability or desire to create offspring has never been a qualification for marriage. From 1970 through 2012 roughly 30% of all US households were married couples without children, and in 2012, married couples without children outnumbered married couples with children by 9%.  6% of married women aged 15-44 are infertile, according to the US Centers for Disease Control and Prevention.  In a 2010 Pew Research Center survey, both married and unmarried people rated love, commitment, and companionship higher than having children as "very important" reasons to get married, and only 44% of unmarried people and 59% of married people rated having children as a very important reason.  Several US presidents never had their own biological children, including George Washington, often referred to as "the Father of Our Country."   As US Supreme Court Justice Elena Kagan noted, a marriage license would be granted to a couple in which the man and woman are both over the age of 55, even though "there are not a lot of children coming out of that marriage." 
A common symbol for the transgender community is the Transgender Pride flag, which was designed by the American transgender woman Monica Helms in 1999, and was first shown at a pride parade in Phoenix, Arizona in 2000. The flag consists of five horizontal stripes: light blue, pink, white, pink, and light blue. Helms describes the meaning of the flag as follows:
Cross-dressing per se is not illegal. Hong Kong law allows the change of legal documents such as the identity card, and passport, but does not allow the birth certificate to be changed. Such change requires sex reassignment surgery, which includes the removal of reproductive organs, effectively rendering the person sterile in exchange for legal recognition of gender identity.
Gay marriage bans cause humiliation and uncertainty for children being raised by same-sex couples. In ruling Texas' gay marriage ban unconstitutional, San Antonio-based federal judge Orlando Garcia stated that the ban "causes needless stigmatization and humiliation for children being raised by the loving same-sex couples being targeted."  Children of unmarried same-sex couples are denied the stability that comes with having married parents, including the guarantee of child support in the case of divorce and an automatic legal connection to both parents.  If no legal relationship is established, the child cannot be sure of receiving financial support from the non-biologically related partner, and is not guaranteed an inheritance if that partner dies without leaving a will. 
Because some bisexual people do not feel that they fit into either the homosexual or the heterosexual world, and because they have a tendency to be "invisible" in public, some bisexual persons are committed to forming their own communities, culture, and political movements. However, since "Bisexual orientation can fall anywhere between the two extremes of homosexuality and heterosexuality", some who identify as bisexual may merge themselves into either homosexual or heterosexual society. Still other bisexual people see this merging as enforced rather than voluntary; bisexual people can face exclusion from both homosexual and heterosexual society on coming out. Psychologist Beth Firestein states that bisexuals also tend to internalize social tensions related to their choice of partners. Firestein suggests bisexuals may feel pressured to label themselves as homosexuals instead of occupying a difficult middle ground in a culture that has it that if bisexuals are attracted to people of both sexes, they must have more than one partner, thus defying society's value on monogamy. These social tensions and pressure may and do affect bisexuals' mental health. Specific therapy methods have been developed for bisexuals to address this concern.

Male bisexuality is particularly presumed to be non-existent, with sexual fluidity studies adding to the debate. In 2005, researchers Gerulf Rieger, Meredith L. Chivers, and J. Michael Bailey used penile plethysmography to measure the arousal of self-identified bisexual men to pornography involving only men and pornography involving only women. Participants were recruited via advertisements in gay-oriented magazines and an alternative paper. They found that the self-identified bisexual men in their sample had genital arousal patterns similar to either homosexual or heterosexual men. The authors concluded that "in terms of behavior and identity, bisexual men clearly exist", but that male bisexuality had not been shown to exist with respect to arousal or attraction. The assertion of Bailey that "for men arousal is orientation" was criticized by Fairness and Accuracy in Reporting (FAIR) as a simplification which neglects to account for behavior and self-identification. Further, some researchers hold that the technique used in the study to measure genital arousal is too crude to capture the richness (erotic sensations, affection, admiration) that constitutes sexual attraction. The National Gay and Lesbian Task Force called the study and The New York Times coverage of it flawed and biphobic.
In the 1940s, the zoologist Alfred Kinsey created a scale to measure the continuum of sexual orientation from heterosexuality to homosexuality. Kinsey studied human sexuality and argued that people have the capability of being hetero- or homosexual even if this trait does not present itself in the current circumstances. The Kinsey scale is used to describe a person's sexual experience or response at a given time. It ranges from 0, meaning exclusively heterosexual, to 6, meaning exclusively homosexual. People who rank anywhere from 2 to 4 are often considered bisexual; they are often not fully one extreme or the other. The sociologists Martin S. Weinberg and Colin J. Williams write that, in principle, people who rank anywhere from 1 to 5 could be considered bisexual.
Most of the world religions have at some points in their histories opposed same-sex marriage for one or more of the following stated reasons: homosexual acts violate natural law or divine intentions and are therefore immoral; passages in sacred texts condemn homosexual acts; and religious tradition recognizes only the marriage of one man and one woman as valid. In the early 21st century, however, Judaism, Christianity, Hinduism, and Buddhism all spoke with more than one voice on this issue. Orthodox Judaism opposed same-sex marriage, while the Reform, Reconstructionist, and Conservative traditions allowed for it. Most Christian denominations opposed it, while the United Church of Christ, the United Church of Canada, and the Religious Society of Friends (Quakers) took a more favourable stand or allowed individual churches autonomy in the matter. The Unitarian Universalist churches and the gay-oriented Universal Fellowship of Metropolitan Community Churches fully accepted same-sex marriage. Hinduism, without a sole leader or hierarchy, allowed some Hindus to accept the practice while others were virulently opposed. The three major schools of Buddhism—Theravada, Mahayana, and Vajrayana—stressed the attainment of enlightenment as a basic theme; most Buddhist literature therefore viewed all marriage as a choice between the two individuals involved.
There is research evidence that the ratio of the length of the 2nd and 4th digits (index finger and ring finger) is somewhat negatively related to prenatal testosterone and positively to estrogen. Studies measuring the fingers found a statistically significant skew in the 2D:4D ratio (long ring finger) towards homosexuality with an even lower ratio in bisexuals. It is suggested that exposure to high prenatal testosterone and low prenatal estrogen concentrations is one cause of homosexuality whereas exposure to very high testosterone levels may be associated with bisexuality. Because testosterone in general is important for sexual differentiation, this view offers an alternative to the suggestion that male homosexuality is genetic.
A reference to same-sex marriage (by the Egyptians and Canaanites) exists in the Talmud. The Book of Leviticus prohibited homosexual relations (Lev. 18:22, 20:13), and the Jewish sages provide the reason for this as being that the Hebrews were warned not to "follow the acts of the land of Egypt or the acts of the land of Canaan". The sages explicitly state: "what did [the Egyptians and Canaanites] do? A man would marry a man and a woman [marry] a woman."
When sex is defined legally, it may be defined by any one of several criteria: the XY sex-determination system, the type of gonads, the type of external sexual features, or the person's social identification. Consequently, both transgender and intersex individuals may be legally categorized into confusing gray areas, and could be prohibited from marrying partners of the "opposite" sex or permitted to marry partners of the "same" sex due to legal distinctions. This could result in long-term marriages, as well as recent same-sex marriages, being overturned.
The governments of Costa Rica and Panama have announced that they will fully implement the IACHR ruling. Additionally, on 11 January, the president of the Supreme Court of Peru and chairman of the country's judiciary, Duberlí Rodríguez, stated that Peru should abide by the decision. On 29 January 2018, Housing Minister Carlos Bruce estimated that same-sex marriage will be allowed in Peru within two years, and several former Supreme Court judges and lawmakers, notably Indira Huilca, stated that same-sex marriage will soon be legal in Peru, regardless. The Peruvian Government, however, has yet to issue a formal decision on the matter.
The causes of transsexuality have been studied for decades. The most studied factors are biological. Certain brain structures in trans women have been found to be similar to cisgender women's as opposed to cis men's, and trans men's have been found to be similar to cis men's, even controlling for hormone use, which can also cause trans people's brains to become closer to those of cis people of the same gender. However, these studies are limited as they include a small number of tested individuals. Brain structure differences have also been part of extensive research on biology and sexual orientation. Studies have also found that both androphilic and gynephilic trans women's brain function and responses are like cis women's and unlike cis men's, or are intermediate between the two. Likewise, studies such as Rametti's have found that trans men have male-like white matter patterns (even before using hormones), regardless of sexual orientation.

One effort to quantify the population gave a "rough estimate" that 0.3 percent of adults in the US are transgender. More recent studies released in 2016 estimate the proportion of Americans who identify as transgender at 0.5 to 0.6%. This would put the total number of transgender Americans at approximately 1.4 million adults (as of 2016).
One of the largest scale uses of social media to mobilize support for same-sex marriage preceded and coincided with the arrival at the U.S. Supreme Court of high-profile legal cases for Proposition 8 and DOMA in March 2013. The "red equal sign" project started by the Human Rights Campaign was an electronic campaign primarily based on Facebook that encouraged users to change their profile images to a red equal sign to express support for same-sex marriage. At the time of the court hearings, an estimated 2.5 million Facebook users changed their profile images to a red equal sign.
Ultimately, I think the Equal Protection Clause does guarantee same-sex marriage in all fifty states. But, as you know, courts have always been strategic. There have been times where the stars were aligned and the Court, like a thunderbolt, issues a ruling like Brown v. Board of Education, but that's pretty rare. And, given the direction of society, for the Court to have allowed the process to play out the way it has may make the shift less controversial and more lasting.
In upholding gay marriage bans in Kentucky, Michigan, Ohio and Tennessee on Nov. 6, 2014, 6th US District Court of Appeals Judge Jeffrey S. Sutton wrote that "marriage has long been a social institution defined by relationships between men and women. So long defined, the tradition is measured in millennia, not centuries or decades. So widely shared, the tradition until recently had been adopted by all governments and major religions of the world."  In the Oct. 15, 1971 decision Baker v. Nelson, the Supreme Court of Minnesota found that "the institution of marriage as a union of man and woman, uniquely involving the procreation and rearing of children within a family, is as old as the book of Genesis."  John F. Harvey, MA, STL, late Catholic priest, wrote in July 2009 that "Throughout the history of the human race the institution of marriage has been understood as the complete spiritual and bodily communion of one man and one woman."  
Frank Kameny soon realized the pivotal change brought by the Stonewall riots. An organizer of gay activism in the 1950s, he was used to persuasion, trying to convince heterosexuals that gay people were no different than they were. When he and other people marched in front of the White House, the State Department and Independence Hall only five years earlier, their objective was to look as if they could work for the U.S. government. Ten people marched with Kameny then, and they alerted no press to their intentions. Although he was stunned by the upheaval by participants in the Annual Reminder in 1969, he later observed, "By the time of Stonewall, we had fifty to sixty gay groups in the country. A year later there was at least fifteen hundred. By two years later, to the extent that a count could be made, it was twenty-five hundred."
Meetings to organize the march began in early January at Rodwell's apartment in 350 Bleecker Street. At first there was difficulty getting some of the major New York City organizations like Gay Activists Alliance (GAA) to send representatives. Craig Rodwell and his partner Fred Sargeant, Ellen Broidy, Michael Brown, Marty Nixon, and Foster Gunnison of Mattachine made up the core group of the CSLD Umbrella Committee (CSLDUC). For initial funding, Gunnison served as treasurer and sought donations from the national homophile organizations and sponsors, while Sargeant solicited donations via the Oscar Wilde Memorial Bookshop customer mailing list and Nixon worked to gain financial support from GLF in his position as treasurer for that organization. Other mainstays of the organizing committee were Judy Miller, Jack Waluska, Steve Gerrie and Brenda Howard of GLF. Believing that more people would turn out for the march on a Sunday, and so as to mark the date of the start of the Stonewall uprising, the CSLDUC scheduled the date for the first march for Sunday, June 28, 1970. With Dick Leitsch's replacement as president of Mattachine NY by Michael Kotis in April 1970, opposition to the march by Mattachine ended.
This lawsuit against the U.S. government was filed in 2010, by Edie Windsor, who had been in a 40-year relationship with her partner, Thea Spyer, and married in Canada in 2007. When Thea died, she left all of the assets in entire estate to Edie Windsor, who sought to claim the federal estate tax exemption for surviving spouses. The exemption was denied, as the IRS did not recognize the women as a married couple. Edie was compelled to pay hundreds of thousands of dollars in estate taxes.
Gay marriage is contrary to the word of God and is incompatible with the beliefs, sacred texts, and traditions of many religious groups. The Bible, in Leviticus 18:22, states: "Thou shalt not lie with mankind, as with womankind: it is abomination," thus condemning homosexual relationships.  In Islamic tradition, several hadiths (passages attributed to the Prophet Muhammad) condemn gay and lesbian relationships, including the sayings "When a man mounts another man, the throne of God shakes," and "Sihaq [lesbian sex] of women is zina [illegitimate sexual intercourse]."  The Catholic Church, United Methodist Church, Southern Baptist Convention, Church of Jesus Christ of Latter-day Saints, National Association of Evangelicals, and American Baptist Churches USA all oppose same-sex marriage.  Two orthodox Jewish groups, the Orthodox Agudath Israel of America and the Orthodox Union, also oppose gay marriage, as does mainstream Islam.   According to a July 31, 2003 statement from the Congregation for the Doctrine of the Faith and approved by Pope John Paul II, marriage "was established by the Creator with its own nature, essential properties and purpose. No ideology can erase from the human spirit the certainty that marriage exists solely between a man and a woman…"  Pope Benedict stated in Jan. 2012 that gay marriage threatened "the future of humanity itself."

The Christian Democratic People's Party of Switzerland (CVP/PDC) started in 2011 with gathering signatures for a popular initiative entitled "For the couple and the family - No to the penalty of marriage". This initiative would change article 14 of the Swiss Federal Constitution and aimed to put equal fiscal rights and equal social security benefits between married couples and unmarried cohabiting couples. However, the text aimed to introduce as well in the Constitution for the first time ever the definition of marriage, which would be the sole "union between a man and a woman". On 19 June 2015, the Parliament recommended that voters reject the initiative. The Federal Council also recommended rejecting the initiative. The Swiss people voted on the Christian Democrats' proposal in a referendum on 28 February 2016 and rejected it by 50.8% of the votes.
Two other studies examined personal reports from LGBT adults and their families living in Memphis, Tennessee, immediately after a successful 2006 ballot campaign banned same-sex marriage. Most respondents reported feeling alienated from their communities. The studies also found that families experienced a kind of secondary minority stress, says Jennifer Arm, a counseling graduate student at the University of Memphis.

The rainbow flag was popularized as a symbol of the gay community by San Francisco artist Gilbert Baker in 1978. The different colors are often associated with "diversity" in the gay community (but actually have literal meanings). The flag is used predominantly at gay pride events and in gay villages worldwide in various forms including banners, clothing and jewelry. Since the 1990s, its symbolism has been transferred to represent the extended "LGBT" (lesbian, gay, bisexual and transgender) community . For the 25th Anniversary of the Stonewall riots, held in 1994 in New York city, a mile-long rainbow flag was created and post-parade cut up in sections that have since been used around the world.
Civil rights campaigning in support of marriage without distinction as to sex or sexual orientation began in the 1970s. In 1972, the now overturned Baker v. Nelson saw the Supreme Court of the United States decline to become involved. The issue became prominent from around 1993, when the Supreme Court of Hawaii ruled in Baehr v. Lewin that it was unconstitutional under the state constitution for the state to abridge marriage on the basis of sex. That ruling led to federal and state actions to explicitly abridge marriage on the basis of sex in order to prevent the marriages of same-sex couples from being recognized by law, the most prominent of which was the 1996 federal DOMA. In 2003, the Massachusetts Supreme Judicial Court ruled in Goodridge v. Department of Public Health that it was unconstitutional under the state constitution for the state to abridge marriage on the basis of sex. From 2004 through to 2015, as the tide of public opinion continued to move towards support of same-sex marriage, various state court rulings, state legislation, direct popular votes (referendums and initiatives), and federal court rulings established same-sex marriage in thirty-six of the fifty states.
In 2006, Israel's High Court of Justice ruled to recognize foreign same-sex marriages for the limited purpose of registration with the Administration of Border Crossings, Population and Immigration; however, this is merely for statistical purposes and grants no state-level rights. Israel does not recognize civil marriages performed under its own jurisdiction. A bill was raised in the Knesset (Israeli Parliament) to rescind the High Court's ruling, but the Knesset did not advance the bill. A bill to legalize same-sex and interfaith civil marriages was defeated in the Knesset, 39–11, on 16 May 2012.
In the United States and Canada, professional organizations including the American Anthropological Association, the American Academy of Pediatrics, the American Medical Association, the American Academy of Nursing, the American Psychological Association, the American Psychiatric Association, the Canadian Psychological Association, the American Sociological Association, the National Association of Social Workers, the American Psychoanalytic Association, the American Association for Marriage and Family Therapy, and the American Academy of Family Physicians have stated that the scientific evidence supports the following conclusions: homosexuality is a natural and normal human sexuality, sexual orientation is not a choice, gay people form stable and committed relationships that are essentially equivalent to the relationships of heterosexuals, same-sex parents are no less capable than opposite-sex parents to raise children, no civilization or viable social order depends on restricting marriage to heterosexuals, and the children of same-sex couples fare just as well or even better than the children of opposite-sex couples.
