To be clear, I used that example because it was the only one I could think of, not for some rhetorical reason (which serves your point anyway, really).

I agree if we could just distill "here's your objective good-at-tennis score" for everybody and draw lines using those numbers, that makes sense. It feels unrealistic? I.e. we already don't do that - it doesn't necessarily feel like 100% an anti-trans thing (orthogonal obviously to the large amount of anti-trans sentiment that generally exists). Maybe Elo for everything?

Yeah for sure.

My point is just that fairness in the Olympics is fake and always has been.

Someones Chromosomes are such a poor way to measure their physical abilities especially when the bar is so high for top athletes in the field.
