Rap has a bad reputation in white circles, where many people believe it consists of obscene and violent anti-white and anti-female guttural. Some of it does. Most does not. Most white listeners don’t care; they hear black voices in a litany of discontent, and tune out. Yet rap plays the same role today as Bob Dylan did in 1960, giving voice to the hopes and angers of a generation, and a lot of rap is powerful writing.
