Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
Martial arts already has weight classes and gender on top. Weight doesn’t cover gender differences
When it comes to martial arts, skill does though. That’s why I got my ass handed to me by a 16 y/o girl who is much smaller than me.
Skill matters. But you get enormous leverage by simply being longer limbed and larger.
Practice a bit and you’ll be beating up 16 year old girls in no time. But even at their peak, women martial artists will struggle with mid-level male peers because they lack the raw physical features that move another body.
It’s the difference between a person firing a pistol and a rifle. Marksmanship only gets you so far. Then you really just need a longer barrel.
With enough practice you could even beat up 17 year old girls!

And for most people it is hard to acknowledge that there is a biological difference to the body of male and female. Same rights to everyone doesnt imply same bodytype for everyone
The problem isn’t that people don’t understand that, the problem is that there are people who don’t fit into the binary distinction
