I think that keeping women's sports sex-segregated is something that motivates a lot of people, from the simple perspective of obvious fairness
I totally agree. Personally I have no interest in sports, they just don't interest me!
But, I am interested in women's rights to single sex sports and will fight for that right. I'm interested in my daughter's right to a level playing field (literally and figuratively). She plays rugby, at the moment with the boys as they're young. But when they're older they're split by sex for very obvious safety reasons on the pitch. It makes a nonsense that if boys are allowed to identify onto the team.
Also I'm interested in single sex spaces more generally.
I don't understand how the left has got itself in such a pickle over gender ideology, how so many seem to have thrown common sense out of the window. It really gives me hope that there are women in Labour (and other parties too) who are hanging on in there and fighting for women's rights.
