Query: To make things short. It is a gay sport.

I seen the documentary and I think that he seems like a nice guy in person and a family man, but the way he fights it is like he's going to kill his opponent when he punch the weak part of the body, the kidneys. His training is art but the way he fights is no art at all. I have experience Grappling styles, similiar to Gracie's Jiu-Jitsu and I think it is no art when you freaking choking someone by the neck and punching the kidneys, you might as well kill the guy.
