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.
No, it doesn’t answer if it’ll be the same for all sports. As others have pointed out archery, shooting, curling, and other sports have men an women competing either separate or together and women can compete at the same level.
As for football, yes, there’s a good chance there’ll be stark differences, but as I pointed out in another comment, not every sport is about raw strength. And, competing against stronger opponents can also raise your ceiling. How far is of course yet to be seen because we don’t have mixed leagues.
And again, the suggestion isn’t “NO MORE SEGREGATION EVER” it’s “should we let them compete against each other”. That means there’ll be a mixed and segregated league. Maybe even, as somebody else suggested, the segregations wouldn’t always be immediately by sex or gender, but by attributes that make sense in that sport e.g weight, muscle mass, height, skill, and so on.
