I think the misinformation comes from the time that Traaa and witches vs patriarchy both had "weirdly similarly timed" attempts at purging commies and going full Lib, but in both cases it failed pretty spectacularly but it still left a fair amount of side effects. It was not long after Chapo got banned and both places got a little more outwardly anti capitalist rather than just cheekily. Traaa was always better than wvp but there was the hilarious "Traa but no commies" sub and then the "Traaa yes commies" response.

I think in general it was just a concerted effort by shitlibs and mods / online brainworm havers to refuse to understand intersectional struggle, but there was both all fuck all success and unfortunately some everlasting weird side effects like this weird occasional opinion popping back up that the commies on those subs were somehow transphobic esp the ones that argued with the shitlibs (Chapo/Hexbear users) because obviously the shitlibs are the main characters in their own story and disagreeing with them makes you the antagonist.
