Yes, I think the thing that's tripping me up is the premise that transwomen are women.
I don't see how one can convince anyone of that, other than claiming it's because of DSDs and then they'd have to pretty much fudge it anyway.
Unless they're going to change the definition of woman. I wouldn't mind someone having a go at that. It's incredibly revealing how sexist they look when they try.
At the very least, I believe this will show up that, when they say woman, they don't actually mean a woman. So that's moving the conversation along a tad, at the very latest.
One of the frustrating parts of this is that people don't actually even get to have the bloody conversation.
