By equal rights, you mean “equal” in relationship to everybody in a category. Physically able women are not allowed to compete in the Paralympics, there's no reason why women with a particular physical advantage couldn’t be excluded from NCAA women’s sports. It’s a matter balancing the rights of various groups in order to get the best result in the real world. The word women has multiple meanings, you can’t just lump them all together and pretend that every woman is identical to every other woman in every way. That might be good for some women but it’s not fair to women.
