"Mixed martial arts" is a misnomer in the first place, martial arts are all very specific forms of self defence of which many are aesthetically great to watch in themselves. The point of most is to minimize contact with the opponent and expend less energy than they do, i.e. wrestling is not a martial art. In reality the UFC crap is a cockfight, especially when it goes to the ground. If it were truly anything goes and as is the case in most real fights, you would be seeing low blows, eye gouges, kicks to a downed opponent etc. I'm not saying they should allow these things but it would at least be consistent with what they are trying to achieve.
