Judith Butler, Bodies that Matter NY Routledge, 1993 (p. 125)
"To claim that all gender is like drag, or is drag, is to suggest that imitation is at the heart of the heterosexual project and its gender binarisms, that drag is not a secondary imitation that presupposes a prior and original gender , but that hegemonic heterosexuality is itself a constant and repeated effort to imitate its own idealizations. that it must repeat this imitation, that it sets up pathologizing practices and normalizing sciences in order to consecrate its claim on originality and propriety, suggests heterosexual performativity is beset by an anxiety that it can never fully overcome, that its effort to become its own idealizations can never be finally or fully achieved, and that it is consistently haunted by the domain of sexual possibility that must be excluded for heterosexualized gender to produce itself. In this sense, then, drag is subversive to the extent that it reflects on the imitative structure by which hegemonic gender is itself produced and disputes heterosexualityís claim on naturalness and originality."
