I just remember him a couple of years or so ago reverse ferreting that he ofc believes TWAW and he was talking about men, not tw
I remember the comment but I don't think it was a reverse ferret. I think he is using sarcasm and sophistry to turn the Genderist arguments against them.
I think his point (and I'm inferring here from a lot of comments on this issue) is that he has no problem with TW being treated as women in most social situations (as none of us do) and that they deserve equal rights, but it's foolish to say that means they are literally a woman for the purposes of changing rooms, sports, sex offences etc.
He's also regularly takes the piss out of 'transwomen' who make no effort to present as women and makes that point that a passing, post-op transsexual is in no way the same thing as a burly bloke with 'she' pronouns- that to treat the latter as a woman, in any sense, is ridiculous.
