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.
You can look up the leaderboards of any of the mentioned sports. It’s not that there’s not any women in there but it’s still virtually all male.
Then there are plenty of examples of top level female athletes losing to males nobody has never even heard of.
