TERF IS NOT a slur. It’s an acronym. It refers to a very specific demographic. Not natal women, not even natal women who are also feminists, our natal feminist women who are also radical, but specifically radical feminist natal women who by words and actions actively exclude trans women from women narratives.
Such women attack us, trivialize our pain, restrict or agency, align themselves with alt-right nasties to pass laws that would erase us from society.
TERF is not a slur the same way that GOP is not a slur. Both of them simply refer to a set of initials. Even KKK is not a slur. The negative connotation is added by the group’s own actions and values, not by any external force.
