UFC light-heavyweight fighter “Suga” Rashad Evans has signed on to a U.S. Supreme Court brief in support of gay marriage.

Outsports.com reported that Evans joined NFL players Chris Kluwe and Brendon Ayanbadejo in an amicus brief urging the Supreme Court to strike down Proposition 8, California's 2008 voter-approved constitutional amendment which defines marriage as a heterosexual union.

“I've never been a homophobe, never understood what that is all about,” Evans said in a statement given to Outsports. “I knew some people who were gay and never cared about their sexuality. But at the same time, I didn't fully understand the issues around gay people until my friend [Ayanbadejo] started telling me about his full public support for gay marriage. We talked about the issue and I decided it's not enough to not be against a minority, if you want things to go better for them you have to speak up with them.”

“I'm a UFC fighter, a macho-type sport. I am a heterosexual guy in a tough macho sport, which is exactly the reason I feel a duty to say I support gay marriage and gay rights.”

“I have nothing to gain personally from supporting this issue, and that's the point. Society as a whole is better when there is equality, and I want to live in a country where everyone has the same rights because we all benefit from that.”

“What people overlook is that is isn't a sex issue, it's a love issue. There's no justifiable reason for trying to get in the way of two people who love each other.”

“I have kids. I don't want them growing up in a society where they, or their friends, could be second class citizens based on which person they fall in love with or who they want to be happy with.”
