Journalist Gail Mathabane likens prohibitions on same-sex marriage to past prohibitions on interracial marriage in the United States. Author Fernando Espuelas argues that same-sex marriage should be allowed because it recognizes the civil right of a minority. Historian Nancy Cott rejects alternatives to same-sex marriage (such as civil unions), reasoning that "there really is no comparison, because there is nothing that is like marriage except marriage."
Same-sex marriage is a civil right. The NAACP (National Association for the Advancement of Colored People), on May 21, 2012, named same-sex marriage as "one of the key civil rights struggles of our time."  In 1967 the US Supreme Court unanimously confirmed in Loving v. Virginia that marriage is "one of the basic civil rights of man."  The White House website lists same-sex marriage amongst a selection of civil rights, along with freedom from employment discrimination, equal pay for women, and fair sentencing for minority criminals.

Different religions have their own views about transgender and transsexual individuals, and not all religions are tolerant toward this community. There is no clear distinction of the two terms in religious texts, and, though most religions have condemned trans behavior, there are cultures and traditions that promote acceptance in some parts of the world, religion notwithstanding.
In 1999, Task Force Pride Philippines (TFP), a network of LGBT and LGBT-friendly groups and individuals seeking to promote positive visibility for the LGBT community was born. Since then, TFP has been organizing the annual Metro Manila Pride March. In 2003, a decision was made to move the Pride March from June to the December Human Rights Week to coincide with related human rights activities such as World AIDS Day (December 1), Philippine National Lesbian Day (December 8), and International Human Rights Day (December 10).
Along with several gay nightclubs, LGBT pride festivals occur annually, as well as other social events including the Hong Kong Lesbian & Gay Film Festival. On each International Day Against Homophobia, a procession is held through the street of Hong Kong to show solidarity. The first IDAHO procession was held in 2005. Political involvement has also become more common in recent years. Several prominent legislators have attend the IDAHO procession and gay pride to show solidarity with the LGBT community.
Societies have resolved the intertwined issues of sexuality, reproduction, and marriage in myriad ways. Their responses regarding the morality, desirability, and administrative perquisites of same-sex partnerships have been equally diverse. Notably, however, by the beginning of the 21st century most countries opted for one of only three legal resolutions to these intersecting problems: to ignore same-sex partnerships, to criminalize them, or to grant them a status similar or equal to that of heterosexual marriage. Many countries have yet to reach a consensus on these issues. (See also marriage law.)
Same-sex couples should have access to the same benefits enjoyed by heterosexual married couples. There are 1,138 benefits, rights and protections available to married couples in federal law alone, according to a General Accounting Office assessment made in 2004.  Benefits only available to married couples include hospital visitation during an illness, the option of filing a joint tax return to reduce a tax burden, access to family health coverage, US residency and family unification for partners from another country, and bereavement leave and inheritance rights if a partner dies.   Married couples also have access to protections if the relationship ends, such as child custody, spousal or child support, and an equitable division of property.  Married couples in the US armed forces are offered health insurance and other benefits unavailable to domestic partners.  The Internal Revenue Service (IRS) and the US Department of Labor also recognize married couples, for the purpose of granting tax, retirement and health insurance benefits.  The US federal government does not grant equivalent benefits to gay couples in civil unions or domestic partnerships.   An Oct. 2, 2009 analysis by the New York Times estimated that same-sex couples denied marriage benefits will incur an additional $41,196 to $467,562 in expenses over their lifetimes compared with married heterosexual couples.  A Jan. 2014 analysis published by the Atlantic concluded that unmarried women pay up to one million dollars more over their lifetimes than married women for healthcare, taxes, and other expenses. 
In 2013, the Supreme Court ruled that the federal government could not deny federal benefits of marriage to same sex couples, if the couple was married in a state that allowed the marriage. Some states do not fully recognize same sex marriage, but they do offer civil unions or domestic partnerships, so that the same sex couples can enjoy some of the same rights and benefits of marriage.
Despite common misconceptions, bisexuality does not require that a person be attracted equally to both sexes. In fact, people who have a distinct but not exclusive preference for one sex over the other can and often do identify as bisexual. A recent study by researchers Gerulf Rieger, Meredith L. Chivers, and J. Michael Bailey, which attracted media attention in 2005, purported to find that bisexuality is extremely rare, and perhaps nonexistent, in men. This was based on results of controversial penile plethysmograph testing when viewing pornographic material involving only men and pornography involving only women. Critics state that this study works from the assumption that a person is only truly bisexual if he or she exhibits virtually equal arousal responses to both opposite-sex and same-sex stimuli, and have consequently dismissed the self-identification of people whose arousal patterns showed even a mild preference for one sex. Some researchers say 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 study, and The New York Times article which reported it, were subsequently criticized as flawed and biphobic. FAIR also criticised the study .
LeVay's (1991) examination at autopsy of 18 homosexual men, 1 bisexual man, 16 presumably heterosexual men and 6 presumably heterosexual women found that the INAH 3 nucleus of the anterior hypothalamus of homosexual men was smaller than that of heterosexual men and closer in size of heterosexual women. Although grouped with homosexuals, the INAH 3 size of the one bisexual subject was similar to that of the heterosexual men.
All states that allow same-sex marriage also allow the joint adoption of children by people of the same sex, with the exceptions of Jalisco, Nayarit and Quintana Roo in Mexico. In addition, Andorra and Israel as well as several subnational jurisdictions which do not recognize same-sex marriage nonetheless permit joint adoption by unmarried same-sex couples: Querétaro and Veracruz in Mexico as well as Northern Ireland and Jersey in the United Kingdom. Some additional states allow stepchild adoption by those who are in a same-sex relationship but are unmarried: Croatia, Estonia, Italy (on a case-by-case basis), Slovenia and Switzerland.
Many Americans felt that the Hawaii court decision represented a serious threat to social stability, and in 1996 the U.S. Congress enacted the Defense of Marriage Act (DOMA). This legislation declared that same-sex marriages would not be recognized for federal purposes, such as the award of Social Security benefits normally afforded to a surviving spouse or employment-based benefits for the partners of federal employees. The act also restated existing law by providing that no U.S. state or territory was required to recognize marriages from elsewhere when it had strong policies to the contrary. Within a decade of the federal act’s passage, almost all the states had enacted laws or constitutional amendments declaring variously that marriage was legally defined as a heterosexual institution, that same-sex marriages from other states would not be recognized, or that same-sex marriage was contrary to the public policies of the state.
J. Matt Barber, Associate Dean for Online Programs at Liberty University School of Law, stated that "Every individual engaged in the homosexual lifestyle, who has adopted a homosexual identity, they know, intuitively, that what they're doing is immoral, unnatural, and self-destructive, yet they thirst for that affirmation." A 2003 set of guidelines signed by Pope John Paul II stated: "There are absolutely no grounds for considering homosexual unions to be in any way similar or even remotely analogous to God's plan for marriage and family... Marriage is holy, while homosexual acts go against the natural moral law."  Former Arkansas governor and Republican presidential candidate Mike Huckabee stated in Oct. 2014 that gay marriage is "inconsistent with nature and nature’s law."

According to Aristotle, although most "belligerent nations" were strongly influenced by their women, the Celts were unusual because their men openly preferred male lovers (Politics II 1269b). H. D. Rankin in Celts and the Classical World notes that "Athenaeus echoes this comment (603a) and so does Ammianus (30.9). It seems to be the general opinion of antiquity." In book XIII of his Deipnosophists, the Roman Greek rhetorician and grammarian Athenaeus, repeating assertions made by Diodorus Siculus in the 1st century BC (Bibliotheca historica 5:32), wrote that Celtic women were beautiful but that the men preferred to sleep together. Diodorus went further, stating that "the young men will offer themselves to strangers and are insulted if the offer is refused". Rankin argues that the ultimate source of these assertions is likely to be Poseidonius and speculates that these authors may be recording "some kind of bonding ritual ... which requires abstinence from women at certain times".
The Vietnamese Government abolished an administrative fine imposed on same-sex weddings in 2013. The policy was enacted on 11 November 2013. The 100,000–500,000 VND ($24USD) fine will be abolished. Although same-sex marriages are not permitted in Vietnam, the policy will decriminalize the relationship, habitual privileges such as household registry, property, child raising, and co-habitual partnerships are recognized.
There is no complete data on the number of same-sex marriages conducted in the United States. Marriages and divorces are recorded by states, counties, and territories, plus New York City and the District of Columbia, but not by the federal government. States such as Oregon do not distinguish between opposite-sex and same-sex marriages in their official records. The legal records on marriage and divorce belong to the states. In August 2016, the Treasury Department estimated the number of same-sex marriages by linking the tax returns of same-sex couples who had filed jointly in 2014 with their Social Security records. (Although this method excluded couples who file singly, these are small in number; of all married couples who file taxes, 97.5% file jointly.) This research showed that in 2014 there were about 183,280 married same-sex couples in the country, or "roughly a third of 1 percent of all marriages" according to the New York Times.
