Gender varianceGender variance or gender nonconformity is behavior or gender expression by an individual that does not match masculine or feminine gender norms. A gender-nonconforming person may be variant in their gender identity, being transgender or non-binary, or they may be cisgender. In the case of transgender people, they may be perceived, or perceive themselves as, gender-nonconforming before transitioning, but might not be perceived as such after transitioning.
Queer theoryQueer theory is the perspective that questions the perception that cisgender and heterosexual identities are in any sense “standard.” It revisits such fields as literary analysis, philosophy, and politics with a “queer” approach. Queer theory is a field of post-structuralism that emerged in the early 1990s out of queer studies (often, formerly, gay and lesbian studies) and women's studies.
HeterosexismHeterosexism is a system of attitudes, bias, and discrimination in favor of female–male sexuality and relationships. According to Elizabeth Cramer, it can include the belief that all people are or should be heterosexual and that heterosexual relationships are the only norm and therefore superior. Although heterosexism is defined in the online editions of the American Heritage Dictionary of the English Language and the Merriam-Webster Collegiate Dictionary as anti-gay discrimination or prejudice "by heterosexual people" and "by heterosexuals", respectively, people of any sexual orientation can hold such attitudes and bias, and can form a part of internalised hatred of one's sexual orientation.
Gender binaryThe gender binary (also known as gender binarism) is the classification of gender into two distinct forms of masculine and feminine, whether by social system, cultural belief, or both simultaneously. Most cultures use a gender binary, having two genders (boys/men and girls/women). In this binary model, gender and sexuality may be assumed by default to align with one's genetic or gamete-based sex, i.e. one's sex assigned at birth.
HomophobiaHomophobia encompasses a range of negative attitudes and feelings toward homosexuality or people who identify or are perceived as being lesbian, gay or bisexual. It has been defined as contempt, prejudice, aversion, hatred or antipathy, may be based on irrational fear and may sometimes be related to religious beliefs. Homophobia is observable in critical and hostile behavior such as discrimination and violence on the basis of sexual orientations that are non-heterosexual. Recognized types of homophobia include institutionalized homophobia, e.
TransphobiaTransphobia consists of negative attitudes, feelings, or actions towards transgender people or transness in general. Transphobia can include fear, aversion, hatred, violence or anger towards people who do not conform to social gender expectations. It is often expressed alongside homophobic views and hence is often considered an aspect of homophobia. Transphobia is a type of prejudice and discrimination, similar to racism and sexism, and transgender people of color are often subjected to all three forms of discrimination at once.
TransgenderA transgender person (often abbreviated to trans person) is someone whose gender identity differs from that typically associated with the sex they were assigned at birth. Many experience gender dysphoria, which they may seek to alleviate through transitioning, often adopting a different name and set of pronouns in the process. They may pursue gender affirming care such as hormone replacement therapy and various gender-affirming surgeries. Not all transgender people desire these treatments and others may be unable to access them for financial, medical or legal reasons.
Social construction of genderThe social construction of gender is a theory in sociology about the manifestation of cultural origins, mechanisms, and corollaries of gender perception and expression in the context of interpersonal and group social interaction. Specifically, the social construction of gender theory stipulates that gender roles are an achieved "status" in a social environment, which implicitly and explicitly categorize people and therefore motivate social behaviors.
Third genderThird gender is a concept in which individuals are categorized, either by themselves or by society, as neither man nor woman. It is also a social category present in societies that recognize three or more genders. The term third is usually understood to mean "other", though some anthropologists and sociologists have described fourth and fifth genders. The state of personally identifying as, or being identified by society as, a man, a woman, or other is usually also defined by the individual's gender identity and gender role in the particular culture in which they live.
LesbianA lesbian is a homosexual woman or girl. The word is also used for women in relation to their sexual identity or sexual behavior, regardless of sexual orientation, or as an adjective to characterize or associate nouns with female homosexuality or same-sex attraction. The concept of "lesbian" to differentiate women with a shared sexual orientation evolved in the 20th century. Throughout history, women have not had the same freedom or independence as men to pursue homosexual relationships, but neither have they met the same harsh punishment as gay men in some societies.
