Homosexuality (attitudes toward)

Heterosexism is a belief or argument that male-female sexuality is the only natural, normal, or moral mode of sexual behavior, and is also used to refer to the effects of that cultural ideology. The word 'heterosexualism' has also been proposed to mean essentially the same thing. This word has been suggested as an alternative to homophobia, in part because it uses a parallel structure to sexism or racism.

Heterosexism should not be confused with heterocentrism, which is an (often subconscious) assumption that everyone is heterosexual, and the attitudes associated with that assumption. Heterocentrism often shows up in unintentional ways in every day life. For instance, when a woman says she is going on a date, many people will ask, "What's his name?" or "Is he cute?" assuming it is a heterosexual date. Nevertheless, these people may not have anything against same-sex dating. In queer theory, the term heterocentrism is closely related to heteronormativity.
