What if he had boots jeans and a flannel shirt? What if his shirts button holes we're on the right? Is that dressing like a woman enough?
That is the point that you keep carefully avoiding. when men actually do themselves up to look like women, nobody even notices when they use the lady's room. it's these obvious dudes like Lia Thomas that, of course, will make any normal woman uncomfortable when he walks in with his junk hanging out while they are undressing.
It is an act of absolute misogyny to pretend otherwise.
