Isn’t the problem not that you can’t make general claims like “only people with uteruses can be called women” etc etc but rather that you can’t target those sorts of things at individuals. Dead naming is (was?) banned I think.I think Jordan Peterson's ban was for something like that, but I could be wrong.
He made it a big stand, because the ban would be reversed if he deleted one tweet, but he refused to delete, ranted on youtube, etc (and has now won)
