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.
Oh, but it does. There are major physical differences between men and women, even if they’re the same weight. Men have greater muscle & bone density. A man of similar physical fitness of the same weight as a woman will be considerably stronger. There wouldn’t even be a competition. It would just be a man beating the shit out of a woman. Nobody wants to see that, despite our desires for equality.
