Your characterization of hip hop shoots the messenger. It's the stories of an oppressed people, if you don't like the violence in their stories, blame their oppressor.

It's the same with porn and the Christian Right. If people feel incomplete and try to fill that gap with a porn habit, the porn is an indicator of a problem, not the problem itself. Filling that gap with right wing propaganda doesn't address the problem, it just changes it into something that can be used for political advantage.

You're missing the root causes here.
