I've seen women who really can fight - men, women, Mack Trucks! Take a look at some of these pugilistic gals and see what a female can do in a fight. Some of the UFC type fights involve ferocious, super tough women. I've heard about some gals fighting men in bare knuckle underground matches (former Soviet Union, 3rd world countries) where they have K.Oed and even killed male opponents. Picture if you will Ms. Ali in a bare fisted fight against some of the local tough guys you know !
