Human bisexuality has mainly been studied alongside homosexuality. Van Wyk and Geist argue that this is a problem for sexuality research because the few studies that have observed bisexuals separately have found that bisexuals are often different from both heterosexuals and homosexuals. Furthermore, bisexuality does not always represent a halfway point between the dichotomy. Research indicates that bisexuality is influenced by biological, cognitive and cultural variables in interaction, and this leads to different types of bisexuality.
Golinski v. Office of Personnel Management (2010–2013). Section 3 of the federal Defense of Marriage Act is found unconstitutional in U.S. district court, which determines that sexual orientation is a quasi-suspect classification requiring the court to apply intermediate scrutiny, that is, to determine whether Section 3 relates to an important government interest. On appeal the case is held in abeyance pending the decision of the U.S. Supreme Court in Windsor, which settles the issues raised in Golinski, the appeal of which to the Supreme Court is then denied.
^ Ring, Trudy (20 December 2012). "Newt Gingrich: Marriage Equality Inevitable, OK". The Advocate. Los Angeles. He [Newt Gingrich] noted to HuffPo that he not only has a lesbian half-sister, LGBT rights activist Candace Gingrich, but has gay friends who've gotten married in Iowa, where their unions are legal. Public opinion has shifted in favor of marriage equality, he said, and the Republican Party could end up on the wrong side of history if it continues to go against the tide.

Political opposition tends to come from social conservatives, often with evangelical Christian ties, who view homosexuality and cross-dressing as signs of immorality. For example, after the court ruled against the unequal age of consent, Hong Kong leader Donald Tsang, a devout Catholic, publicly opposed the court's decision and fought for an appeal until 2006. However, most political parties and individual politicians have tended to avoid making public statements in favour of LGBT rights, although this has slowly begun to change.
In September 2016, President Bachelet stated before a United Nations General Assembly panel that the Chilean Government would submit a same-sex marriage bill to Congress in the first half of 2017. A same-sex marriage bill was submitted in September 2017. Parliament began discussing the bill on 27 November 2017, but it failed to pass before March 2018, when a new Government was inaugurated.
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."  
Perhaps because systems of religion and systems of civil authority often reflect and support each other, the countries that had reached consensus on the issue by the early 2000s tended to have a single dominant religious affiliation across the population; many such places had a single, state-sponsored religion. This was the case in both Iran, where a strong Muslim theocracy had criminalized same-sex intimacy, and Denmark, where the findings of a conference of Evangelical Lutheran bishops (representing the state religion) had helped smooth the way for the first national recognition of same-sex relationships through registered partnerships. In other cases, the cultural homogeneity supported by the dominant religion did not result in the application of doctrine to the civic realm but may nonetheless have fostered a smoother series of discussions among the citizenry: Belgium and Spain had legalized same-sex marriage, for instance, despite official opposition from their predominant religious institution, the Roman Catholic Church.
I like movies where bisexuals come out to each other together and fall in love, because these tend to be so few and far between; the most recent example would be 2002's lovely romantic comedy, Kissing Jessica Stein. Most movies with bi characters paint a stereotypical picture.... The bi love interest is usually deceptive (Mulholland Drive), over-sexed (Sex Monster), unfaithful (High Art), and fickle (Three of Hearts), and might even be a serial killer, like Sharon Stone in Basic Instinct. In other words, the bisexual is always the cause of the conflict in the film.
The legal issues surrounding same-sex marriage in the United States are determined by the nation's federal system of government, in which the status of a person, including marital status, is determined in large measure by the individual states. Prior to 1996, the federal government did not define marriage; any marriage recognized by a state was recognized by the federal government, even if that marriage was not recognized by one or more states, as was the case until 1967 with interracial marriage, which some states banned by statute.
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. 
Historically, bisexuality has largely been free of the social stigma associated with homosexuality, prevalent even where bisexuality was the norm. In Ancient Greece pederasty was not problematic as long as the men involved eventually married and had children. In many world cultures, homosexual affairs have been quietly accepted among upper-class men of good social standing (particularly if married), and heterosexual marriage has often been used successfully as a defense against accusations of homosexuality. On the other hand, there are bisexuals who marry or live with a heterosexual partner because they prefer the complementarity of different sexes in cohabiting and co-parenting but have felt greatly enriched by homosexual relationships alongside the marriage in both monogamous and "open" relationships.
