This seems to be a black and white issue for many, always Yes or always No.
As with most thigns I feel the truth is somewhere in the middle.
It’s a spectrum
IMO
A biological man who never underwent puberty and never got the benefits of higher testosterone etc. should be allowed in women’s sports.
But, someone like Usain Bolt, who because of undergoing male puberty has bigger bones than he would have had if he didn’t, should never be allowed to compete in women’s sports.
Where we draw the line, I don’t know, but I don’t think it’s black or white.
What testosterone level you were at during puberty has a big impact on the size of your bones. So it’s not that simple.
People who had high testosterone during puberty have much bigger hands than people who didn’t, hand size has a impact on sports.
What sports do you get an advantage with bigger hands? Are we going to get rid of cisgender women who have big hands too for those reasons too? I’m not even sure where you’re getting this hand size thing anyway
I’d think swimming, but a better example might be basketball.
Going through male puberty would make you taller than you would have otherwise been, and in basketball beign taller gives you an advantage.
With swimming, one would have to push through more body with the same muscle mass (or even less due to suppressed testosterone instead of natural cis woman levels)
Basketball will have some of the same issues to a lesser extent, although the natural different variations will still make up for it. My sister (Cisgender) is taller than I am (Trans girl)
