No more men’s and women’s league, no more “gender eligibility” requirements, a common dresscode, same standards and rules for all.
Edit: since it looks like people missing the word let: the suggestion isn’t to force desegregation. It’s to allow it or even make it the default. Someone else made a good suggestion: segregate by attributes specific to the sport. In boxing it’s weight class, in basketball it could be height, in biking it could even be doped and non doped. Sex and gender need not be the very first thing to segregate by.
Care to expand?
It would make most sports incredibly boring to watch, as well as frustrating for many athletes. Boring sport means less money, which would also mean less teams overall.
Why would it be boring?
I have, in other comments and the description of the thread too. Anything specific you would like to know?
