I think everyone is getting Blue Vet wrong.
He is just saying that logically We men are stronger than Women, that is just how nature made us. Up to that point I agree with him.
But I still think Diana wins, even if that muscle logic were to somehow apply, she has her gear and warrior born training plus her reflexes and speed.
Even if she were 3 times weaker than the male opponent (which I don't think she is) She is much much faster than him.
And when you have someone who is 3 times weaker than you trading 15 punches to 1 against you (which you may or may not connect) then it becomes pretty clear who has the advantage.
