I am reading "Unpacking Queer Politics" by Shiela Jeffreys (2003), at the recommendation of someone here to my question of How Did This Happen. I hope you all don't mind the occasional post as I go. The passage below shocked me, re my ignorance at how long the transing of lesbians has been going on.
Woman-loving does not survive well in male-dominated queer politics. In a mixed movement the resources, influence and just sheer numbers of men give them the power to create cultural norms. As a result, some lesbians became so disenchanted with their lesbianism, and even their femaleness, that there are presently hundreds, if not thousands, of lesbians in the UK and the USA who have ‘transitioned’ - i.e. adopted the identity not just of males but of gay males with the help of testosterone and mutilating operations (Devor 1999).
