This would be a regular occurrence, would it? I mean, your understanding of gender dynamics would suggest that it is. So could you cite me examples of where it's happened, then? Or indeed any example, at all?
Yes, it is indeed a miserable fact that men can impose themselves on women and threaten them, and lots will like doing that. But I think we need to try to understand the enemy here. Think of it from their point of view. There are many, many situations where it's easier to do that than in women's changing rooms. They only need to follow a woman down a street. Or catch her in a hallway, in an office, or in any number of places, where they could get away with it a million times more easily. Why would they want to risk going into a women's changing room to do that? With other women possibly there, with cameras on them going in and out? Some say: 'Oh yes, but supposed 'trans women' could do that!' But why go to the trouble of disguising themselves as women in order to do that, when they can do it so much more easily elsewhere? It makes no sense whatsoever.
Well, whatever. If there are cases of this happening - or if there's even just one case of it happening - I'll think again. But to me, right now, this is one of the silliest things to get scared about I've ever come across.
