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.
Your question blurb literally says “no more men and women’s leagues, no more gender requirements.”
That is not compatible with segregated leagues.
It really seems like you didn’t know that some sports men and women already play against each other and some they don’t and are now trying to argue for a bizzarely complex system rather than admit that hey, you hadn’t thought something through or you didn’t know something.
