LGBT are the initials of the words Lesbian, Gay, Bisexual and Transgender. Strictly speaking, it groups people with the sexual orientations and gender identities related to these four words, as well as the communities formed by them. The term has been the result of an evolution in which letters were added in order to include various communities discriminated by their sexual identity. Since I clarify something these people were previously quite discriminated only for their equal taste or both to their sex, to the truth that I do not see bad: we are all free to fall in love and want to be with the people we love, nobody can come back in those we are all free of expressions and taste, and that's what LGBTQ is for, to celebrate these people in June and make them feel good about themselves.
I think this is fabulous because it makes them feel more confident with them same by showing the world who they really are since many young people right now are hiding the truth from their families for fear of their rejection. I say this because I have a friend who is afraid to tell his mother what he really is Gay because his father says he does not want any of his children to be that because it is something not from God. Something that I see quite badly because then my friend hides on something that is not but I give you a lot of advice, to confront your father and tell him the truth, he cannot live in a world like this without saying who he really is.
Within this progressive trend, the acronym "LGBT" has acquired a broad meaning, also encompassing communities not included in those four letters, emphasizing sexual diversity and gender identities, including people who have a sex, sexual orientation or gender not accepted by heteronormative and binary tradition, instead of applying it exclusively to people who define themselves as lesbian, gay, bisexual or transsexual. However, some individuals and communities literally encompassed by the acronym LGBT or its extensions, have expressed dissatisfaction with it. Some individuals in one group may feel that they have no relationship with individuals in the other groups encompassed and find persistent comparisons offensive. Some argue that the causes of transsexual and transgender people cannot be grouped under the same denomination as those of homosexual and bisexual people. This finds its expression in the current of "gay and lesbian separatism", which maintains that lesbians and gays they should form a distinctive community and separate themselves from the other groups that are normally included.
Other people, even though they see the term with favor, because it includes different identities and orientations, and because it is widely used, think that it is not perfect and that is politically correct. The term LGBT does not generate a consensus among all. For example, some argue that the problems and goals of transgender, transsexual, and transvestite people are not the same as those of homosexuals, lesbians, and bisexual people, in the idea that transgender people and transsexuality have to do with gender identity or the fact of feeling male or female, not sexual orientation. Instead, LGB issues are perceived as a matter of sexual orientation or attraction, not identity. These distinctions have been made within the context of political action, where the goals of LGBs may be perceived as distinct from goals of transgender and intersex people (for example, legislation on gay marriage among others). Similarly, some intersexes want to be included in LGBT groups and prefer the term "LGBTI" while others insist that they are not part of the LGBT community and wish they were not included as part of the term.
The opposite situation occurs in the stream of "gay and lesbian separatism" (not to be confused with lesbian separatism), which hold that lesbians and men gain (or form) a distinctive and separate community from the other groups that they are normally included in the LGBTQ sphere. There is no specific number or organization to be called a movement, separatists are an active, vocal and significant element in many parts of the LGBT community.
