My comment under the video (sometimes I can't help myself)
You are comparing Boxing, Kickboxing etc with an mma fighter assaulting someone. Why is there no ref? You said yourself in boxing, guy goes down, "wakes up" and you can knock him down again. That is actually more damaging and injurious. People have literally been BEATEN TO DEATH...that is ok with you?
Kung Fu uses weapons...you may not hit anybody with them but you simulate it. Why do you pretend to cut people with swords? Thats demented.
You truly lack understanding of what martial arts are.
