It's overwhelmingly MEN who denigrate athletic women by calling them 'manly'. I've literally never heard a woman say that outstanding female athletes like Martina and Serena have an 'unfair physical advantage' over other women. The only talk of unfairness in relation to women's sport I can remember before the present insanity concerned Eastern European female athletes who, decades back, were put on testosterone at massive cost to their own health. Those women certainly had an unethical advantage over their fellow females, but nowhere nearly as unethical or dangerous as letting men compete against women. The old-time dopers must be furious; it would have been so much easier to cheat these days. No need to feed young girls drugs, just field an entire squad of bearded, penis-ed athletes, some of whom call themselves women.
