Gay man assulted by coworkers, DA does nothing

Change.org petition here. Looks a lot to me like they are ignoring what is happening to this guy because he's male. If this were a female getting sexually abused this way by men or women, I am sure the DA would be all over it. Men have the right to live lives free of assault and abuse by people of either sex, and it's time the powers-that-be knew it. Excerpt:

'While working at the Shaw Group in Baton Rouge, Louisiana, I was sexually assaulted by four male co-workers who perceived that I was gay. But the District Attorney's office has refused to take the case. I believe this is because they don’t take male-on-male sexual assault seriously. Now, I’m calling for a state and federal investigation to hold my abusers accountable and prevent this from happening to anyone else.
...
When I finally had enough of the abuse, I went to the police. The four men were charged, but the District Attorney refused to take the case because I was unable to appear before a Grand Jury in August. I was only given two days notice before the hearing and my request for a delay so I could speak with a rape therapist before having to speak publicly about what happened to me was denied.

I’m calling on my Attorney General in Louisiana, Buddy Caldwell, and Thomas E. Perez, Assistant Attorney General for DOJ Civil Rights Division, to investigate the case. I know they’ll find the truth.

Talking about what happened to me isn’t easy. But I know that somewhere, someone else is going through the same thing.'
