A belief or attitude that assumes heterosexuality is the only normal sexual orientation, often leading to discrimination against those who are not heterosexual.
Heterosexism can create an unwelcoming environment for LGBTQ+ individuals.
Heterosexism is formed from "hetero-" (from Greek "heteros", meaning different or other) and "sexism" (from "sexus", meaning sex or gender, combined with the suffix "-ism", indicating a belief or ideology). The term refers to the belief that heterosexuality is the only valid sexual orientation, often leading to discrimination against non-heterosexual orientations.
Think of 'hetero-' meaning 'different' and 'sexism' relating to 'gender' or 'sex' — this helps you remember that heterosexism is the belief that only heterosexual relationships are valid.
