Smirking bloke waiting and listening for you to pee.
Blokes stalking the sanitary bins to take whatever you just put in there, and the wetter and still warm the better, putting them on and walking around in them for the thrill. Show your lovely, sensitive, empathic person some of the stuff from the forum about putting your used tampon up his bum.
Show them the one about the self identified teenager in Scotland who recently shoved a teenaged girl into the cubicle and tried to make her take her trousers off to assault her.
Talk about women with trauma histories, the 1 in 4 women who were sexually assaulted by a male before the age of 20, women with disabilities not able to prioritise other people's realities or not see what's in front of them without becoming panicked and distressed, older women, women with cultures and faiths that say they cannot toilet or undress in the presence of a male. And the many, many women who will not feel comfortable to pull their pants down or get in a shower with someone they perceive as male on the other side of a flimsy door. Usually because of their life experience of males and their pattern recognition skills, not because of random prudery, so it's extremely rude/insensitive/oblivious/thick of this person to just dismiss all women not happy about this as being silly.
There's no way to be all woke about this bullshit without basically saying, all men's right to use whatever facility makes them happy is more important than the safety, privacy, dignity and access (never mind happiness) of all women. And it's fine to exclude women from all facilities so that males can have more options.
If you believe that, you believe that people with penises are more important than people with ovaries. And there's a word for that.
