I really do not see her problem or concern. Was this not settled back in the 70’s with the Billie Jean King versus Bobby Riggs match? I thought it was settled that women could beat men, that it was not big deal? Well, let’s see how it works out now.
What was at stake wasn't that a woman could beat a man, but that a man could beat a woman young enough to be his daughter.
Turns out he couldn't (though he did beat Margaret Court, who was about Billy Jean's age).
It would have been nice if Billy Jean had continued the experiment by playing a man her own age, but she was smart enough not to.
