While my initial knee-jerk reaction to this was to delete it, I realized that that would be a silly idea. In fairness to that line of thinking, this map could be considered quite offensive. However, video games are a medium through which we do things we would never do in real life. Many players enjoy Grand Theft Auto, but they would never think to steal a car, shoot innocent people, resist arrest, or kidnap prostitutes in real life. Most of what we do in Halo is shoot other players, but that isn't indicative of actual violent urges on our behalf.
So, after looking at it that way, I think it would be unfair to treat this map any differently from any other. I would encourage anyone who might feel initially offended by it to think on the above point as well.
