Well there are rules in MMA. Comparing it too being stoned is way off point . But as soon as the opponent is hurt and can not intelligently defend himself the bout is over.
But its difficult to guage, Ive seen someone landing about 20 full punches to the face is less that 10 seconds
However if you have issues with MMA then I'm guessing boxing is not one you like either? Professional Wrestling in fact can be just as brutal if not more. The people that compete in MMA are really more of athletes than just people who just think they can kick anyone's ass.
Wrestling is staged, and in boxing people where thick gloves, so its not as disturbing. There is no elbow or kneebone thrust into your nose, or eye socket type of contact allowed? Like I said how is irreversible damages, unconsciouslness, death avoided in these fights?
Am I missing something here?
