Heterosexism
-Discrimination or prejudice against lesbians or gay men by heterosexual people.
An earlier definition of this term is: 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 instinct. The word 'heterosexualism' has also been proposed to mean essentially the same thing. [2] This word has been suggested as an alternative to homophobia [3], in part because it uses a parallel structure to sexism or racism. The intent of heterosexism is the examination of the cultural bias towards non-heterosexuals rather than individual bias, which is the focus of homophobia.
