Heterosexism describes a behavioral system that denies, denigrates, and stigmatizes any nonheterosexual form of behavior, identity, relationship, or community. Heterosexism is often misused as synonymous with homophobia. However, heterosexism is the systemic display of homophobia within societal institutions, created through the assumption that the world is heterosexual and that heterosexuality is superior and normative. In the 1990s, queer scholars began referring to this as normative heterosexuality or heteronormativity. Heteronormativity illustrates the cultural dichotomy that exists between heterosexuality and homosexuality.
Heterosexism is analogous to sexism and racism, with similar parallels in the way it approaches issues in mainstream culture. Heterosexism uses the invisibility of homosexuality to minimize its existence while attacking it personally and institutionally when it becomes more visible. Historically, heterosexism has been found in large societal institutions like religion and law.

Homophobia is considered to be the fear of gay, lesbian, bisexual, or queer people or same-gender sexual behaviors. Homophobia is believed to result from learning and reinforcement over the life span; tolerance and acceptance of sexual minorities are also considered learned behaviors. The development of negative attitudes is often the result of both explicit teachings in an individual’s family, educational, or social setting (including some cultural and religious teachings) and implicit messages about the worth or characteristics of sexual minorities. Silence about sexual minorities’ experiences and the invisibility of sexual minority role models may also contribute to the development of homophobia.

“Transphobia” refers to attitudes and beliefs about transgender people that stigmatize and antagonize people within the transgender community. The word “transgender” (or “trans”) is often used as an umbrella term to refer to any gender-nonconforming person, behavior, expression, or identity, including people who cross-dress, are transsexual, are genderqueer, are drag queens and kings, as well as a host of other terms that people use to categorize their gender.

Many cultures traditionally referred to those who identified outside the gender binary as a third gender, but these individuals are commonly referred to as nonbinary within Western society. Nonbinary is an umbrella term to represent individuals who do not identify as exclusively female or male, including varying degrees of female and male, neither female nor male, another gender, or a combination of genders. The nonbinary umbrella includes genderqueer, genderfluid, bigender, trigender, among others as well as nonbinary as a gender, sometimes abbreviated as NB or enby.
