LGBTQ is an initialism for lesbian, gay, bisexual, transgender and queer or questioning. It is an umbrella term, broadly referring to all sexualities, romantic orientations, and gender identities which are not heterosexual, heteroromantic, or cisgender.
Sexuality and gender identity-based cultures are subcultures and communities composed of people who have shared experiences, backgrounds, or interests due to common sexual or gender identities. Among the first to argue that members of sexual minorities can also constitute cultural minorities were Adolf Brand, Magnus Hirschfeld, and Leontine Sagan in Germany. These pioneers were later followed by the Mattachine Society and the Daughters of Bilitis in the United States.
Coming out of the closet, often shortened to coming out, is a metaphor used to describe LGBTQ people's self-disclosure of their sexual orientation, romantic orientation, or gender identity.
The LGBTQ community is a loosely defined grouping of lesbian, gay, bisexual, transgender, and queer or questioning individuals united by a common culture and social movements. These communities generally celebrate pride, diversity, individuality, and sexuality. LGBTQ activists and sociologists see LGBTQ community-building as a counterweight to heterosexism, homophobia, biphobia, transphobia, sexualism, and conformist pressures that exist in the larger society. The term pride or sometimes gay pride expresses the LGBTQ community's identity and collective strength; pride parades provide both a prime example of the use and a demonstration of the general meaning of the term. The LGBTQ community is diverse in political affiliation. Not all people who are lesbian, gay, bisexual, or transgender consider themselves part of the LGBTQ community.
Heteronormativity is the concept that heterosexuality is the preferred or normal sexual orientation. It assumes the gender binary and that sexual and marital relations are most fitting between people of opposite sex.
LGBTQ slang, LGBTQ speak, queer slang, or gay slang is a set of English slang lexicon used predominantly among LGBTQ+ people. It has been used in various languages since the early 20th century as a means by which members of the LGBTQ+ community identify themselves and speak in code with brevity and speed to others.
A sexual minority is a demographic whose sexual identity, orientation or practices differ from the majority of the surrounding society. Primarily used to refer to lesbian, gay, bisexual, or non-heterosexual individuals, it can also refer to transgender, non-binary or intersex individuals.
A pride flag is any flag that represents a segment or part of the LGBTQ community. Pride in this case refers to the notion of LGBTQ pride. The terms LGBTQ flag and queer flag are often used interchangeably.
Over the course of its history, the LGBTQ community has adopted certain symbols for self-identification to demonstrate unity, pride, shared values, and allegiance to one another. These symbols communicate ideas, concepts, and identity both within their communities and to mainstream culture. The two symbols most recognized internationally are the pink triangle and the rainbow flag.
LGBTQ movements in the United States comprise an interwoven history of lesbian, gay, bisexual, transgender and queer social movements in the United States of America, beginning in the early 20th century. A commonly stated goal among these movements is social equality for LGBTQ people. Some have also focused on building LGBTQ communities or worked towards liberation for the broader society from biphobia, homophobia, and transphobia. LGBTQ movements organized today are made up of a wide range of political activism and cultural activity, including lobbying, street marches, social groups, media, art, and research. Sociologist Mary Bernstein writes:
For the lesbian and gay movement, then, cultural goals include challenging dominant constructions of masculinity and femininity, homophobia, and the primacy of the gendered heterosexual nuclear family (heteronormativity). Political goals include changing laws and policies in order to gain new rights, benefits, and protections from harm.
Various issues in medicine relate to lesbian, gay, bisexual, transgender and queer (LGBTQ) people. According to the US Gay and Lesbian Medical Association (GLMA), besides HIV/AIDS, issues related to LGBTQ health include breast and cervical cancer, hepatitis, mental health, substance use disorders, alcohol use, tobacco use, depression, access to care for transgender persons, issues surrounding marriage and family recognition, conversion therapy, refusal clause legislation, and laws that are intended to "immunize health care professionals from liability for discriminating against persons of whom they disapprove."
Lesbian, gay, bisexual, transgender (LGBT) affirming denominations in Judaism are Jewish religious groups that welcome LGBTQ members and do not consider homosexuality to be a sin. They include both entire Jewish denominations, as well as individual synagogues. Some are composed mainly of non-LGBT members and also have specific programs to welcome LGBT people, while others are composed mainly of LGBT members.
Intersex people are born with sex characteristics that "do not fit the typical definitions for male or female bodies". They are substantially more likely to identify as lesbian, gay, bisexual, or transgender (LGBT) than endosex people. According to a study done in Australia of Australian citizens with intersex conditions, participants labeled 'heterosexual' as the most popular single label with the rest being scattered among various other labels. According to another study, an estimated 8.5% to 20% experiencing gender dysphoria. Although many intersex people are heterosexual and cisgender, and not all of them identify as LGBTQ+, this overlap and "shared experiences of harm arising from dominant societal sex and gender norms" has led to intersex people often being included under the LGBT umbrella, with the acronym sometimes expanded to LGBTI. Some intersex activists and organisations have criticised this inclusion as distracting from intersex-specific issues such as involuntary medical interventions.
Sexual diversity or gender and sexual diversity (GSD), refers to all the diversities of sex characteristics, sexual orientations and gender identities, without the need to specify each of the identities, behaviors, or characteristics that form this plurality.
In the past most lesbian, gay, bisexual, transgender, and queer (LGBTQ) personnel had major restrictions placed on them in terms of service in the United States military. As of 2010 sexual orientation and gender identity in the United States military varies greatly as the United States Armed Forces have become increasingly openly diverse in the regards of LGBTQ people and acceptance towards them.
Queer erasure refers to the tendency to intentionally or unintentionally remove LGBT groups or people from record, or downplay their significance, which includes lesbian, gay, bisexual, transgender, and queer people. This erasure can be found in a number of written and oral texts, including popular and scholarly texts.
Homonormativity is the adoption of heteronormative ideals and constructs onto LGBT culture and identity. It is predicated on the assumption that the norms and values of heterosexuality should be replicated and performed among homosexual people. Those who assert this theory claim homonormativity selectively privileges cisgender homosexuality as worthy of social acceptance.
