Really Why Is This Even Our Problem?! It's a man thing.
Yes, and they're making it a woman's problem rather than doing the obvious logical thing which is a third space. Which makes it seem very likely that actually this isn't really about being threatened in the mens but about riding roughshod over womens' consent and enjoying making them feel uncomfortable / scared.
The TRA line is that the feelings of transwomen are more important than the feelings of any woman who suffers from PTSD / has been raped or simply feels uncomfortable with a penis in the woman's changing room in front of themselves or their daughters.
It is deeply creepy. I think self ID is a predators' charter.
This thread has made me think a lot about this. I know that there are many transsexuals, like Miranda Yardley who - like most women (and indeed men) - consider the feelings of others and who, for that reason, like Miranda, don't use women-only spaces. However, the debate is being driven by those who clearly hate women and hate women having boundaries or talking about their biology or doing anything that they haven't given permission for. It's all about control.
Given this is the case, I think I'd actually feel happier if self ID comes in in the normal men's changing room. Where the men who care about other peoples' feelings and are just there for a swim are. We always hear NAMALT. It's true, most men are decent. Given who's driving the whole self-ID thing, I think I'd rather take my chances in with the men. The ones who don't want to make women uncomfortable and would likely step in to stop someone who is - say - using their physical size to intimidate women and children. I can't believe it's come to this, but honestly, that's how I'd feel.
At which point, we will just have one unisex changing room after all. And maybe that's the point. I don't know.
