Sexism against who? Do you mean against men since they were not historically allowed to play women’s sports sports, while women were allowed to play men’s? Correct me if I’m wrong, but women are allowed in nearly all of the world’s major leagues. They just don’t perform competitively enough to be drafted.

To be clear, I was saying sexual dimorphism goes much deeper than just humans. In most animal species, there is a huge difference in size and strength between males and females. Humans are not unique in this, that’s all I was saying.
