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.
Ah, the typical “it’s always worked this way”. Well, there’s no need to elaborate then. Why ever change? Everything is perfect as it is.
You’ve expressed no reason to change, so yes, stay the same until there’s a reason to spend millions of dollars and upend established systems.
