How feminist is taking the piss out of minorities? Not very.
@WidowWadman except it isn't, is it? It's taking the piss out of a group of largely very privileged people who have appropriated the language of oppressed groups, and who then demand those oppressed groups centre and service them.
Under ridiculous current TRA definitions I would count as both queer and trans (although I don't use that language because, as the OP says, "queer" has been appropriated by straight people, and although I'm "agender", like many - most? - other women here, I don't call myself agender because I think gender identity theory is all bollocks) and I think that blog is brilliant.
