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
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
