Online roots of the term TERF originated in the late 2000s but grew out of 1970s radical feminist circles after it became apparent that there needed to be a term to separate radical feminists who support trans women and those who don’t. Many anti-trans feminists today claim it’s a slur, despite what many see as an accurate description of their beliefs. They now prefer to call themselves “gender critical,” a euphemism akin to white supremacists calling themselves “race realists.”
Katelyn Burns on.
From a longer article about the rise of TERFs and their alliance with the ultra-right but, mostly… oooh Burns burns, lol.
[Obvious content warning due to the subject matter, in that the linked article does discuss TERF beliefs and history, though it’s by no means sympathetic.]
