You are all liars if you claim that there is absolutely NO rap song you enjoy, not even in the slightest. There is at least one Lil Jon, guilty pleasure track in your head that is DYING to be blasted on your speakers. So what's telling you no?
Rap degrades women. It glorifies violence (including violence against women) and uses crude language, etc.
Sure, but so do the majority of things that occupy our culture - we have major movie companies churning out film after film that fail to pass the Bechdel test (A Million Ways to Die in the West, for example) that are just as "crude" and "violent" as American rap culture. It’s nearly impossible to find something in our mainstream culture that hasn’t been soaked in a heavy coat of cultural misogyny - it’s just that the rap world is more explicit.
