Exactly right.
But the protestations above as to the coyness and pearl clutching by those who don't want to catch sight of dicks in their changing areas are hilarious. Most women who are bi or heterosexual don't grab their rosary beads and utter 10 hail Mary's if they clap eyes on a cock. It's a fucking ridiculous point to make.
Female genitalia can't be used as a weapon to invasively enter the body of a man. Waving it about in others' spaces, were this even possible, would not be viewed as what it clearly is when men do the same: an implicit threat against women that their appendage can be weaponised against them, and a reminder of the fact because it gives them a sexual thrill. (Oddly enough, in many years of using female changing facilities I have never once seen a vulva on display). Then there's the worrying statistic that men who behave in this way go on to more serious sexual offences later.
Do it in a public park and you'll be arrested. But try the same thing on with women in a state of undress, in an enclosed space they can't easily get away from, and that's apparently a-okay. Traumatised victims of sexual offences matter, and should not have to give up their swimming activities because a sub-set of men wants to use them as human support vessels.
Men are entirely the cause of this issue. Men are the ones who have weaponized their dicks against the bodies of those who are smaller and less physically strong. If other born males who identify as women have an issue with this, that issue was caused by their own sex, and should be taken up with them.
Women didn't cause this. We can't control it. We can't cure it.
