That doesn't mean they don't exist.

Simply put, TERFs hate transgender women for two reasons. First, TERFs want to eliminate gender roles and they believe that transgender women shore them up. Second, TERFs define transgender women as men based on the anatomical circumstances of their birth and believe that "actual" women must be protected from these men in order to be safe.

TERFs despise transgender women so much, in fact, that they end up contradicting their most beloved political commitments in order to reject them. On the Radfem 2013 website, they profess: "We believe that gender is a destructive hierarchy, which harms women and needs to be abolished." But on the same page, they write:
We welcome radical feminists and those women who want to learn more about radical feminism. It is women-only because we believe that we need to organise autonomously in order to fight for our freedom from patriarchy.

And, indeed, the penis is at the center of TERF politics. One of the most famous images of Catherine Brennan shows her holding a sign, addressed to transgender women, reading: "Sorry about your dick." Over six decades after Simone de Beauvoir refuted the Freudian notion that "anatomy is destiny," the folks in Brennan's camp vigorously defend it in all its reductiveness. It's past time to stop listening to feminists whose politics have an expiration date of 1949 and it's high time to start fashioning radical communities into safer places for trans* folks.
