That’s what I though too. In fact, I’m sure that was part of her lawyers’ argument – that she was born, brought up and identifies as female.
I really hate this case, because I can’t see a “fair” solution. CS is an incredible athlete, but it does seem that she has a genetic advantage over other women that means competition against her is less than fair. And yet banning her from competing or making her take hormone surprising drugs doesn’t seem fair either. I honestly don’t know what I think is the right judgement. Maybe, as others have said, different categories?
