For sure, I have no clue how all that works but there has got to be a better way to do it than just separating by genders.
The “problem” is that gender is a spectrum and there doesn’t exist any real metric to discern or categorize people into a social binary. Honestly, I’m surprised this topic is even popping up again when I thought this was hashed out several years and Olympics ago when right wingers were bringing this up back then. Trying to categorize and disqualify women by testosterone content just doesn’t work. This is all ultimately a method of trying to police and control women’s bodies.
In a similar vein, why aren’t men looked at in the same manner. Why not say that any particular man either has too much estrogen and is either too womanly or not manly enough to qualify or compete. It’s because these people aren’t looking for fairness, safety, or any other dog whistle they might cry about. It’s all just about controlling women.
