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.
It was good enough for the ancient Greeks
Probably boost viewership a good bit
More environmentally friendly, no micro plastics from the synthetic fabrics
Avoids the inevitable arguments about which teams uniforms are too revealing or look stupid or whatever
One less expense for the smaller/less well-funded teams to worry about, and harder to argue that one team has an advantage because they have better equipment
Probably would scare away some of the prudish religious assholes, good riddance.
Sucks to be you if you play a winter sport though.
