I used to be a libfem up til recently. Then I saw a post cross my dash, from another liberal feminist I followed. It said: “Is there an equivalent term for gay men who reject trans men, like terf? We need one.” That was when I realized that people really DO use “terf” to mean “lesbian.” Or more accurately, to mean “fucking dyke bitch.” That girl on my dash didn’t even realize she’d just revealed her hand.
