HETEROSEXISM — [Noun] The assumption or prejudice that heterosexuality is the default or superior sexual orientation, often leading to discrimination against non-heterosexual individuals. From heterosex(ual) (pertaining to heterosexuality) + -ism (denoting a system or ideology); modeled on sexism. Unlike "homophobia" (which specifically denotes fear or hatred of homosexual individuals) or "heteronormativity" (which describes the cultural assumption that heterosexuality is the norm), heterosexism is the quiet machinery of exclusion—the unspoken rules, the raised eyebrows, the forms with only two checkboxes. It is the wedding invitation that assumes a plus-one means "husband," the coworker who asks a lesbian when she’ll "meet the right man," or the textbook that illustrates "family" as one mother, one father. Beneath the surface of these small enforcements lies the insistence that anything else is not just different, but less.
