But the threads aren't full of 'I have no problem with transwomen, it's self ID I'm concerned about'.
Many of the threads are full of (insert numerous names of well known transwomen) is a MAN. So and so is a MAN. No matter what lengths anyone goes to, what diagnosis they have, what medical intervention they have (though said in a more offensive way) I will never say they are not a MAN. I will never allow them to appropriate my pronouns etc etc. I will always call them a MAN.
So it looks very much like that a lot of posters do have a 'problem' outside of proposed changes to self ID.
You (not literally you) see 'biological facts'. Others see 'hatred and transphobia'. Neither of the sides will be able to convince the other that they are wrong. One side can't see hate, the other can't not. So they are pointless, repetitive arguments.
That's why there's such a division here currently.
