I think part of what I don't understand with the idea that it SHOULD be open to everyone is... ... well ... that's just not how sports work anyway? Like the idea is that it's "unfair" for a transwoman not to be able to compete in a sport she likes because of something that's beyond her control at birth.

BUT that's inherent to sports? You want to be a professional gymnast but you have wideset hips? Tough **** you can't. I want to be a jockey but I'm 6'2? Nope sorry pal it's not happening.

etc.

There are all sort of barriers to sports, so I don't think another "Well I'd like to do _____, but..." is a huge problem or a huge discrimination.
