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.
In Finland we have lower physical requirements for women to get into the police academy. I think it’s safe to say that with equal requirements we wouldn’t have a single female police officer in the entire country.
I’d expect a similar thing to happen in sports. When it comes to physical strenght men have a massive advantage over women. It would be the women who this screws over.
