Is it sexist to object to female tennis players shrieking and screaming through their matches? Not at all. It’s biology. Women have higher-pitched voices than men on the whole (that’s real women) and their shrieks are more piercing and would normally be taken as a sign that they’re in deadly danger and in need of help; usually from some big, strong bloke(s). So no wonder they’re upsetting when they’re done just to put the opponent off.
