I think that’s definitely it for some - I was talking to someone just like this the other day. A lovely person in lots of ways but shockingly naive, to the point of being bigoted in her own way.
She went full Layla Moran when I asked her how she could distinguish between “genuine” “TW” and predators exploiting the loophole (who she had acknowledged exist) and said quite angrily, you can just sense these things, you can see it in their eyes!
She said she genuinely wouldn’t have a problem getting changed/showering alongside a penis bearer - and I know she regularly uses a facility which is all completely open plan - because if he identifies as a woman, he is a woman, afasc.
But couldn’t say what a woman is, of course.
She also, interestingly, thought it was impossible for gay men to be misogynistic. I remember thinking that gay men were all allies to women myself - because they didn’t want to sleep with us and often got treated like crap by men themselves, I guess.
But that was a very long time ago and I was very young when I thought that; experience soon taught me that while some gay men are utterly lovely, there are others whose misogyny is quite breathtaking.
I was surprised that she as a middle aged woman hadn’t got to that realisation.
Maybe that’s part of it. She seemed to pride herself on having lots of “LGBTQ” friends, including of course the obligatory “my lovely trans friends™️”; maybe she’s been exceptionally lucky in her male friends.
Or maybe she just doesn’t always realise when her male friends are taking the piss/using her. I had a gay male BFF I thought the world of for years, until I finally copped onto the fact that I, like all the other women in his life, was just a service human to him.
As you say, Wellies, these women have no clue!
