'Fight Church'

I occasionally hear some complain that they wish Christianity were tougher, meaner, and more masculine. That’s always struck  me as odd, but some Christians are acting on that desire. From USA Today:

Finally, someone is making a movie that answers an important question:

"Can you love your neighbor as yourself and at the same time knee him in the face as hard as you can?"

That's a direct quote from Paul Burress, a pastor in Rochester, N.Y., who believes mixed martial arts can help bring people together. He and fellow fighters are profiled in Fight Church, a doc from directors Daniel Junge and Bryan Storkel.

Check out the trailer for Fight Church, which features both children and adults trying to beat the hell out of their opponents in the kickboxing ring, which somehow relates to their Christian faith.

I understand the relationship between athletics and faith, but do you think this is comparable? Mixed martial arts is quite controversial; its brutality is illegal in some states. Is this compatible with Christianity, or an aberration? Can one compete in mixed martial arts despite his faith? What about because of it?
