That having been said...
She said that when she spars with men, she said she always has problems with them. Their sheer size and muscle mass means that blows that would injure an ordinary female, just bounce off of the men. Approximately, "Men are always bigger, faster, and able to absorb more punishment".
Again, this coming from a woman who is exceptional at hand-to-hand. Your average 5'4" Jane Smith with a little extra weight... or even in good shape ... with nothing more than basic training, is going to get her head handed to her, every time.
But, as you pointed out, reality has little to do with liberal fantasies.
Of course a woman like her, who is expertly trained, can take advantage of certain things - potential balance differences, using opponents weight against them, etc. But given her realistic view she would not ever willingly go up against a well trained guy in a real fight.
