"Personally, I have always preferred the term heterosexist for things like the rape-is-not-about-sex position, because its relationship to the term sexism reflects its investment in male dominance, while heterocentric has always seemed more appropriate for things like the point about battering because it is talking more about a point of view rather than a desire to perpetuate male dominant ideology."
"The heterosexist was a leader of the campaign to pass the anti gay marriage initiative and write discrimination into the state constitution."
"While you may not recognize it, we live in what is called a heterosexist society."
