One thing I do not get about Genderism is that they reject the belief that it's the physical body that makes a human a man or a woman, yet still believe some humans are men and some humans are women.
But if we hadn't had the example of two physical sexes, why would we have come up with the idea of Man-people and Woman-people in the first place?
I find it very weird that they can't or won't tell us what definition they use for Man, Woman etc ("it's a gotcha" , "blah blah blah" etc) yet demand such very specific provisions for Men and Women. How can they be so certain "trans women must use women's spaces/compete in women's sports" when without a definition of woman it's impossible to even explain why women need women only spaces or women only sports?
