So, I fully support trans people competing with cisgender people in sport. I also think there's loads of sports where you could gender desegregate it - basically all the sports that don't rely on strength and size.
So I said that bit, but then I also said that if you desegregated sports like swimming, football, rugby, etc etc, then you would never see a woman in a top team or on the podium at the Olympics ever again. Is that not factual? Even Ledecky, who is a ridiculously good swimmer, would not even make the men's swimming final at the Olympics.
I think you could desegregate sports at lower levels too - I've seen it done and experienced it. I was in a middle tier team in cricket with a bunch of dinguses, and the sometimes Women's A Team players would join our matches. They were as capable or better than the blokes most of the time. However, these women went on to play internationally, on TV, picking up contracts and stuff by playing against other women. If it was desegregated she'd be playing with shmucks like me who never even really liked cricket.
Am I wrong?
Ideally, most sports should be stratified by weight or height.
The world's strongest 5'4 swimmer will straight up never be able to compete with someone with the stature of Michael Phelps.
I suspect that wrestling a similarly sized woman would be more of a challenge than wrestling someone a weight class or two down.
How significant are disparities in strength when controlling for weight? I'm not sure it's all that much especially if you factor out women's greater fat distribution into boobs & butts.
Men are still stronger in the same weight class. It's still a significant enough disparity to impact a ton of sports. Look at weightlifting for example. Even in the same weight classes, men lift significantly more.
