In a series of incisive essays, Serano draws on gender theory, her training as a biologist, her career in queer activism, and her own experiences before and after her gender transition to examine the deep connections between sexism and transphobia. She coins the term transmisogyny to describe the specific discrimination trans women face-and she shows how, in a world where masculinity is seen as unquestionably superior to femininity, transgender women's very existence becomes a threat to the established gender hierarchy. Now updated with a new afterword on the contemporary anti-trans backlash, Whipping Girl makes the case that today's feminists and transgender activists must work to embrace and empower femininity-in all of its wondrous forms-and to make the world safe and just for people of all genders and sexualities.
