You know, I read stuff like this, and I just cannot believe that there are women who walk among us, that are this blinkered.
There have been hundreds of documented cases, of men (dressed as women) attacking women in women's changing rooms, bathrooms and places that were previously single sex spaces. Also, peeping Toms, looking over the top of bathroom stalls etc.
You absolutely would care what was between a person's legs, if you were in a bathroom alone, with a man who wanted to rape you.
You absolutely should care, if you have daughters/nieces, who might find themselves in the bathroom with hairy Mike, whilst you sit obliviously at a table outside chatting with your friends.
Well, you should care for womankind in general, but I can see that's not going to happen here.
I could honestly cry with frustration, when women deny what's happening to us.
If mentally unwell men want to pretend they are women, open a third set of facilities for them. It's not women's problem to solve, and they don't get us to budge over and make space for them in what should be safe and private female only spaces.
