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.
Not true. Some countries allow it on a national level, but many do not. I believe The Netherlands allows it, but only at lower competition levels.
I think FIFA forbids it entirely, but I’m not entirely sure.
You are right, it’s not allowed in the FIFA World Cup. I didn’t know.
