Women are not natural "fighters" in that traditional sense (i.e. combat sports).
They have their strengths, and their natural gifts and abilities. It seems like trying to have a "female version" of a man's sport is trying to pound a square peg through a round hole.
That may not be "PC", but since women's MMA is less popular for being "cool" and more popular for the "hot women" in it, I think my point validates itself.
MMA is 99.9% popular because of the male fighters. Will that ever change, not likely. Why? Because watching two women smash each other is just plain gross and wrong.
Please consider England in your prayers!
