Heterosexism is a set of beliefs, practices and social arrangements that treat heterosexual attraction and relationships between men and women as normal, natural, or superior to other kinds of sexual and romantic relationships. At the individual level it can appear as assumptions about who will date or marry whom; at the institutional level it shapes laws, policies and cultural norms that favor opposite‑sex couples. For a simple formulation, see discussions of sex and love between men and women as sexual relations and as romantic relationships.
Characteristics and common forms
Heterosexism is less an isolated prejudice than a system: it normalizes heterosexuality through language, media representation, family law, religious teachings and everyday expectations. It includes assumptions such as "everyone is heterosexual until told otherwise," the privileging of opposite‑sex parents in custody or adoption contexts, and workplace benefits structured around heterosexual partnerships. Cultural transmission and institutional reinforcement are key mechanisms — for discussion see perspectives on societal teaching and cultural norms influence.
History and development
The term and critique of heterosexism grew out of late 20th‑century activism and scholarship that analyzed how laws, medicine and religion marginalized non‑heterosexual lives. Critics showed that many social practices labeled "neutral" actually assume heterosexuality as the default. Over time academic fields such as sociology, gender studies and law have examined how those defaults produce unequal outcomes.
Impacts, examples and who is affected
Heterosexism can cause direct and indirect harms: discriminatory hiring or housing practices, erasure of same‑sex relationships in media and policy, and social stigma. It frequently overlaps with and contributes to hostility toward people who are gay (gay), lesbian (lesbian), bisexual (bisexual) or asexual (asexual). Examples include assuming a patient has an opposite‑sex partner, excluding same‑sex couples from family leave benefits, or curricula that only present opposite‑sex relationships.
Relations and distinctions
- Heterosexism vs homophobia: heterosexism names a systemic privileging of heterosexuality; homophobia often denotes hostility or fear directed at gay people. See comparative concepts homophobia and biphobia.
- Heterosexism and sexism are related but distinct: both are systems of power; sexism privileges a gender hierarchy, while heterosexism privileges sexual orientation norms. They intersect with other forms of bias such as sexism, misogyny and transphobia.
Addressing heterosexism requires both individual change (challenging assumptions, inclusive language) and structural reforms (equal rights in law, representation in media, inclusive institutions).
