What SentientCushion and AssignedPerfectAtBirth said.
I engaged with a couple of them before the attack happened. They were incredibly patronising and seemed to think that if only I met a trans person I'd understand and we could all just get along. They were very excited about having a dialogue because they'd 'never met a TERF before' - yes, those actual words with a big shiney eyed cultish smile, followed by genuine surprise that I was not happy to be called a TERF.
They exist in a bubble. Feminists I talk to, here and elsewhere, are well aware of what transactivists are saying - what their arguments are, what stats they will quote, what language they like to use, what language will cause them a total shitfit etc. TA's arguments are incredibly predictable once you've read or heard a few.
These youngsters appeared genuinely surprised that TERF was not a word feminists use about ourselves and they had apparently never heard the reasons why so many of us find cis offensive. They seemed genuinely surprised that I was advocating for everybody to be able to dress how they want, do what they want etc. regardless of gender stereotypes.
I was surprised at this because when I've come across that sort of thing online I've always assumed it was faux naivete. I now think there are a proportion of TAs who maybe really have never heard the feminist position properly - because they block us straight away and fear denunciation if they engage with someone whose cousin's dog was rumoured to once have been walked by a TERF.
So I'm going to try to be a bit more patient with those who do engage, in the hope that they're just young and in a bubble and still have a chance to grow the fuck up
