Josh Barnett, one of the most celebrated MMA fighters in history, discusses his thoughts on the gay community and how it's changing the sport. He claims that fighters used to "grasping" their opponents barely had to touch them, but now due to gay fighters, the sport is becoming homosexuality-infused and "way more gay."
