I suspect because this being what has happened in “most sex segregated sports” is a very very bold assertion. In which of those sports are women holding top positions? I mean women athletes are awesome, but the idea that separation happens because the poor men can’t keep up is just… I don’t know, maybe I’m a confused old man.

But I thought it was so that women could compete at the top levels of their sport in sports where their times, weights, etc. are not really proximal. They should of course be combined where the physical implications are negligible, but the idea that what’s preventing that is that the men just can’t compete with the women seems strange to me.

But is there some support for that?
