As a former competitive swimmer who does not worry about this issue, it really gets my goat when some flabby, non-athletic male is whining about it. First of all, they aren't women and they are not athletes. It's sort of like the men getting involved in the abortion issue. The number of trans women who are involved in this issue is very small. Maybe we might run into one trans athlete in our whole careers. Oh well, I'm not going to die if they beat me. As a senior, I used to get beat by a tall girl with big hands and big feet who was a freshman but that's what happens sometimes. Michael Phelps had a bunch of physical traits that really helped him. ADHD can apparently help - which Michael has - also Simone Biles, Michael Jordan and Pete Rose.
