LGBT or GLBT is an initialism that stands for lesbian, gay, bisexual, and transgender. In use since the 1990s, the term is an adaptation of the initialism LGB, which was used to replace the term gay in reference to the LGBT community beginning in the mid-to-late 1980s. Activists believed that the term gay community did not accurately represent all those to whom it referred. The initialism has become mainstream as a self-designation; it has been adopted by the majority of sexuality and gender identity-based community centers and media in the United States, as well as some other English-speaking countries. The term is used also in some other countries, particularly those which languages use the initialism, such as Argentina, France and Turkey.
The initialism LGBT is intended to emphasize a diversity of sexuality and gender identity-based cultures. It may be used to refer to anyone who is non-heterosexual or non-cisgender, instead of exclusively to people who are lesbian, gay, bisexual, or transgender. To recognize this inclusion, a popular variant adds the letter Q for those who identify as queer or are questioning their sexual identity; LGBTQ has been recorded since 1996.
LGBTQIA to intentionally include and visibilize the Queer, Intersex and Asexual communities under our umbrella.
The initialisms LGBT or GLBT are not agreeable to everyone that they encompass. For example, some argue that transgender and transsexual causes are not the same as that of lesbian, gay, and bisexual (LGB) people. This argument centers on the idea that transgender and transsexuality have to do with gender identity, or a person’s understanding of being or not being a man or a woman irrespective of their sexual orientation. LGB issues can be seen as a matter of sexual orientation or attraction. These distinctions have been made in the context of political action in which LGB goals, such as same-sex marriage legislation and human rights work not including transgender and intersex people, may be perceived to differ from transgender and transsexual goals.
**The difference between an acronym and initialism is that the abbreviation formed with initialisms is not pronounced as a word, rather you say the individual letters, such as FBI (Federal Bureau of Investigation), CIA (Central Intelligence Agency), and DVD (Digital Video Disk).
