LGBT is an initialism that stands for "lesbian, gay, bisexual, and transgender". It may refer to anyone who is non-heterosexual, non-heteroromantic, or non-cisgender, instead of exclusively to people who are lesbian, gay, bisexual, or transgender. A variant, LGBTQ, adds the letter Q for those who identify as queer (which can be synonymous with LGBT) or are questioning their sexual or gender identity. Another variation, LGBTQ+, adds a plus sign "represents those who are part of the community, but for whom LGBTQ does not accurately capture or reflect their identity". Many further variations of the acronym exist, such as LGBT+ (simplified to encompass the Q concept within the plus sign), LGBTQIA+ (adding intersex, asexual, aromantic and agender), and 2SLGBTQ+ (adding two-spirit for a term specific to Indigenous North Americans). The LGBT label is not universally agreed to by everyone that it is generally intended to include. The variations GLBT and GLBTQ rearrange the letters in the acronym. In use since the late 1980s, the initialism, as well as some of its common variants, functions as an umbrella term for marginalized sexualities and gender identities.
LGBT is an adaptation of LGB, which in the mid-to-late 1980s began to replace the term gay (or gay and lesbian) in reference to the broader LGBT community. When not inclusive of transgender people, the shorter LGB is still used. (Full article...)
Homosexuality is a sexual attraction, romantic attraction, or sexual behavior between members of the same sex or gender. As a sexual orientation, homosexuality is "an enduring pattern of emotional, romantic, and/or sexual attractions" exclusively to people of the same sex or gender. It "also refers to a person's sense of identity based on those attractions, related behaviors, and membership in a community of others who share those attractions."
Along with bisexuality and heterosexuality, homosexuality is one of the three main categories of sexual orientation within the heterosexual–homosexual continuum. Scientists do not yet know the exact cause of sexual orientation, but they theorize that it is caused by a complex interplay of genetic, hormonal, and environmental influences and do not view it as a choice. Although no single theory on the cause of sexual orientation has yet gained widespread support, scientists favor biologically based theories. There is considerably more evidence supporting nonsocial, biological causes of sexual orientation than social ones, especially for males. There is no substantive evidence which suggests parenting or early childhood experiences play a role with regard to sexual orientation. While some believe that homosexual activity is unnatural, scientific research shows that homosexuality is a normal and natural variation in human sexuality and is not in and of itself a source of negative psychological effects. There is insufficient evidence to support the use of psychological interventions to change sexual orientation. (Full article...)
