I think that all terfs who call themselves "females" should watch this video

This is page 45 in the book "Females" by Andrea Long Chu.
In the United States the man known as the father of gynecology, J. Marion Sims, built the field in the antebellum South, operating on enslaved women in his backyard, often without anesthesia — or, of course, consent. As C. Riley Snorton has recently documented, the distinction between biological females and women as a social category, far from a neutral scientific observation, developed precisely in order for the captive black woman to be recognized as female — making Sims's research applicable to his women patients in polite white society — without being granted the status of social and legal personhood. Sex was produced, in other words, precisely at the juncture where gender was denied. In this sense, a female has always been less than a person.
Acknowledgement of this, however, would require terfs to give a fuck about black women. Which they never do.
