DERF

Acronym for "Drag Exclusionary Radical Feminist". A person who espouses to be a feminist but who does not believe that men dressed in Drag should be included in the fight for equality, especially in employment or salary parity. This rabid exclusion of an entire class of women is usually a belief based on misplaced uptight morality.

DERFS are not helping the fight against the patriarchy
