Individuals always have advantages over others—that’s what the Olympics is in theory about, to find the most talented individuals within groups. But groups also have advantages—that’s why the groups exist, and that’s what the statistics deal with. Are you arguing that the Y chromosome does not give anyone any advantage? If so, you should be on the side of canceling women’s sports and creating new categories.

Oh, I believe you’re wrong about the women who was misidentified. They thought she had male hormones. There was no genetic test done then. To the best of my knowledge, I mentioned the only case in the literature of someone with a Y chromosome who gave birth.
