I don't think it's okay to scrutinise anyone's clothed genitals. But we don't have to agree,
This is how the gaslighting is done.
We don't want men in our spaces.
They're not men.
We don't want transwomen in our spaces because they are biological men.
No they're not, they're the same as you.
Here's one showing his penis hanging free, at exactly the same time as he is telling girls they are bigots for objecting to him in their intimate space.
OMG that's just pervy, stop looking at his genitals.
And on and on.
It's really little wonder that women go back to beginning and re-draw the line in the sand, with the determination to ignore preferred pronouns, etc.
