Vegas Casinos warned to ban rappers.

According to the Movable Buffet, casinos and night clubs in Las Vegas have been warned by authorities to ban rappers "especially 50 cent" because of escalating violence whenever they perform. They claim their whole act is based on violence. The Gaming Control Board has even gone a step forward by sending a note to casinos reminding them that they are soley responsible for any regulatory violations that happen within or outside of a nightclub located within any casino.....Can this be categorized as being racist if you ban a specific genre? Rap isn't the only genre out there that perpetuates violence. Why single out rappers only?
