Boxer Emile Griffith isn't a name that's widely known these days - even to hardcore boxing fans - and that's because he was light years ahead of his time. Griffith was in the ring from 1958 through to 1977 and was a world welterweight and middleweight champion in his prime. He was also a bisexual, although he didn't agree with that term.
Griffith once told Sports Illustrated that he hated the fact that people put labels on sexuality, saying, "I don't know what I am. I love men and women the same." His life's biggest controversy came when he fought Benny Paret in 1962. Paret used a homophobic slur towards Griffith before the fight and touched his buttocks. An incensed Griffith had to be held back from attacking his opponent. During the fight, he knocked Paret out hard. Paret died ten days later in hospital without ever regaining consciousness.
