I was saying we could create the missing liberal spaces ourselves. ThePantser said we couldn't because we're being called out as sexist when we do that. The only example for that being "boy scouts" which I suppose means BSA, an organization with massive sexual abuse and bullying problems (according to Wikipedia). No idea how they are supposed to be "liberal".

Whether the girl scouts accept other genders or not has no relevance for that argument. And if it would be fair for them to do that is a completely different discussion because girls are hit by sexism in a completely different way than boys.

the use of the term “gender identity” there implies it’s more for trans people

No, it doesn't.

if there was a recurring women-only Minecraft party or something and there was never one for men, I’d be upset about that.

And again you are completely ignoring any arguments about why these spaces might make sense.
