So, let me check that I've got this straight. Are you saying that the way to deal with the issues of inner city ghettos, gang violence, gun crime, drugs and police brutality is to ban rap music?
As I recall, hip-hop/rap music sprang out of a need for disenfranchised youth of low-income areas to have a "voice" and speak out about the social, economic and political realities of their lives. However, it appears that rap music doesn't agree with your sensibilities and you somehow think that it's the music that the issue rather than being a symptom of a major problem in the U.S.
I wonder how you would want "Black" people to respond to negative outside influences? Maybe tip their hat and say "Yes Masser"?
Your attitude reminds me of the Christian right back in the late 70s when they were complaining about backwards satanic messages in rock music. The problem isn't the music and trying to ban freedom of expression is part of the problem.
