bone and muscle density is still different, and distributed differently

I think people who say things like this don’t actually know any post- or even mid-transition people.

You’re gonna be downvoted because you’ve put zero thought or effort into your argument. There are undeniable physical differences between humans regardless of dominant sex hormone, separating sports by gender necessarily forces members of both groups to compete against people that they don’t have a snowball’s chance in hell of beating. Tall women have a massive advantage over short men and short women, the smart thing to do is let people compete with other people that are actually physically comparable. Tiny men vs tiny women is fair, giant women vs giant men is fair. The bone/muscle density thing is bullshit, simple as.
