In Texas a trans male high school wrestler was forced to compete in the female division. He had been on testosterone for over a year and as wrestling does have a testosterone advantage...the results were predictable.
I believe he only competed to show them how unfair it was.
Trans men also often have to jump through a lot of hoops to prove they are trans because, unfortunately, some people use testosterone to dope. It's understandable, but annoying...especially for the person I'm thinking of, a fairly elite horseback rider. (ZERO advantage to higher testosterone there).
Look, this isn't about fairness. This is about forcing trans people back into their assigned gender. The propaganda makes that hard to see, which is the point. All of this fuss about trans women in sport is calculated to turn cis women against trans women. So is the bathroom panic.
