Despite your insistence to the contrary, nobody I'd associate with wants anyone to be getting sexual gratification by leering at others in dressing rooms. Because believe it or not, we're good people who don't tolerate sex pests. That has nothing at all to do with gender or sexual orientation and everything to do with not being a shitty person.
Sadly, it's beyond obvious that the right's performative outrage over men in women's dressing rooms never really had anything to do with protecting women, and everything to do with ostracizing trans folks. I'll leave you with a quote from a guy recently welcomed back to Twitter by Musk himself:
"I’ll go backstage before a show, and everyone’s getting dressed and ready and everything else. And you know, no men are anywhere. I’m allowed to go in because I’m the owner of the pageant. And, therefore, I’m inspecting it. I’m inspecting it. I want to make sure everything is good."
He went on, as if he was in the dressing room, "'Is everyone okay?' You know, they’re standing there with no clothes. And you see these incredible looking women. And so I sort of get away with things like that."
