People single out rap/hip-hop too much. Rock/Metal is just as 'dangerous' and profane, if not even worse. Going back further, all of the ancient tales and epics are no better either. The Odyssey is about violence, getting wealth, sleeping with women and drinking just like most modern music. Going even further, many people misunderstand hip-hop culture. If you actually listened to the lyrics and think of what led to this, you would get a better perspective. Hip-Hop is the minorities' music that started out when American slaves could not afford instruments so they had to use their lyricism as their instrument. Political controversy in music has almost always been led by hip-hop because hip-hop is where minorities express their rage against society, touch upon these issues and albeit at times just unleash their anger in a strange, gonzo sort of fashion like NWA. Look up songs like 'Brenda's Got a Baby' and 'Trapped' by Tupac or 'Fight the Power' by Public Enemy and 'F*** Da Police' by NWA.
