I don't agree with your statement about stronger, but less fit winning, less fit can't last a match. The williams sisters are very fit for example, but not muscle bound, it's just their type of body. My example of 'fit' is able to endure, and all the woman tennis players we see on tv can endure, or they wouldn't make it to the top. I don't know 'any' women 'crying' equality in sports, they play against each other, and haven't asked to play the men, your point doesn't make any sense. I don't have a clue why there is best of 3 for women and best of 5 for men, tennis federation would have to answer that question, I'm just assuming it's because the women aren't strong enough to play that long, 'at their best'., just my opinion.
Michelle Wee played against men in golf, (sometimes),did very well till she had a serious wrist injury, took a while healing, she tried again but lost her confidence, then her game suffered, she is making good comback now on the women's tour, it's not necessary for her to play the men, doesn't prove anything to either sex. She hits the ball as long, and longer than lots of men, but she still belongs with the women, she played excellent in the soheim cup.
Sponsors wanted her in tournaments to 'bring' in more money because it
drew more viewers.
Again I will say, 'strength alone is not excellence'. Men are stronger than women, always have been always will, no one can change that.
Maybe 5 sets rather than 3 is too hard on their bodies, physically, muscles
and bones, could lead to injuries, just my assumption, don't really know for
sure. Women are smaller, muscles and bones are smaller.
