I believe that UFC, Pride, KOTC, et al...are great SPORTS. MMA is very valid on the streets. I'm pretty sure no strict MA would call for picking up a rock and using it to end a fight. But in a real fight there are truly "no hold barred". Sport is just that, sport. MA is a very old form of self defence. MMA is a philosophy that, I believe, uses what ever works at the moment to let me survive the next 5 minutes.
