The women were in the fenced off play area, not one of them or even one child left the area or went anywhere near the piece of grass surrounded on three sides by bushes where the men were. As I walked by on the path with my DGS a few of the men looked up at me. It wan't a welcoming look. I suppose perhaps some of you imagine that this sort of segregation doesn't happen here, but it does.
It does. I've seen it too, both in a park (possibly the same one) and on a train.
It's wrong, and it's unpleasant, and no, I don't support or endorse that sort of segregation. I think the people concerned have a right to live as their faith dictates, if that is what they want to do, but not to impose it onto others, particularly the majority group in a wider society.
I also think that a minority group, such as non-binary people in a women's clothes shop shouldn't impose their own ways onto others, though.
It isn't easy to balance different needs. The park situation resembles the way you keep saying that the law supports women who don't want to be amongst transwomen who are undressing or whatever. The Jewish men you mention had no right to tell you to leave the park, or to keep away from 'their' area, but they were able to make you feel uncomfortable enough to want to do so, and I do understand how that feels.
Why do you think that that is wrong, yet when transwomen do it to women it is simply living their lives and asking for inclusion?
