Thing is, most of us women who are women (no qualifier needed here), who are of a certain age, have come through the slings and arrows insults stage, and lots of us, no matter how we 'present', would tolerate a 'you look like a man' insult pretty sturdily.
It's interesting, isn't it, that males (usually in their 30s/40s/50s who are presenting/identifying/believing they are women) are the ones who think slinging such an insult will touch the sides.
I call projection. Because it would hurt them to have the trans/male thing slung at them.
They just don't get it.
Oooh, you look a bit like a man.
Er, OK, whatever, I know who I am. Whatever! Any-hoo, about this female single sex spaces, sports, prisons thing...
Meanwhile, in gender-fluid world, what indeed looks 'like a man' or 'trans? (Are they saying 'trans' is hinting at 'male-bodied'?!) Cos, surely, none of us know what a 'man' and a 'woman' is, what with all this sciencey stuff telling us it's not a thing anymore? Just your feelz.
