Whipping Girl: A Transsexual Woman on Sexism and the Scapegoating of Femininity is a 2007 book by the gender theorist, biologist, and writer Julia Serano.

[1] The book is a transfeminist manifesto that makes the case that transphobia is rooted in sexism and that transgender activism is a feminist movement.

In a collection of essays, Serano seeks to deconstruct Western societal narratives about trans women, including those of academia, medicine, and the media.

"[5] Serano uses the term cissexual assumption to describe the belief among cisgender people that everyone experiences gender identity in the same way.

The fourth and final tenet of this model states that "each of these inclinations roughly correlates with physical sex, resulting in a bimodal distribution pattern (i.e., two overlapping bell curves) similar to that seen for other gender differences, such as height.

In the introduction to Whipping Girl, Serano says that she chose the title "to highlight the ways in which people who are feminine, whether they be female, male, and/or transgender, are almost universally demeaned compared with their masculine counterparts.
