Your first sentence, including “ gender critical feminist” is a red flag. The only people being criticized are trans people. That is why the original acronym, TERF, is a better description. The only qualm I have is that it should be just gender critical, eliminating the word feminist, which you are not if you debate or argue about trans existence or validity. Dressing this up in academic speech and other niceties does not alter the bigotry. No surprise you would mention LGB, which is an obvious and vile attempt to marginalize trans people even more.
