I suppose that you have some statistics to back up your assertion that ‘gangsta rap’ causes young White men to commit violent crime at the same rates of young Negro men.
As someone that listened to NWA in 88 when it came out I can tell you at 16-17 I wanted to be like what NWA was saying so we would go fight and tell the police off and do all kinds of crazy stuff. So yes some gangsta rap does influence even whitey to do stupid things...
