This is a well-written post but it's a strawman.
The thread title and opening post seemed to be about the rhetoric in the music playing directly into the hands of racist people who aren't from the community. From what I gathered from the OP, there was no implication that the music inspired crime in the community or really inspired anything for that matter; just that the music seems to play into the anti-black racist thought process.
"I really hate nikkas, I'm a nazi" is a perfect example. It's understood to be wordplay on the surface by people in the culture, but that kind of wordplay doesn't exist in artforms made by other ethnic groups in the mainstream..."I really hate kikes, I'm a nazi" or anything like it is not on the radio, on television or any other platforms for 'entertainment' because the Jews have power over the rhetoric surrounding them in mass media. Lines like that by Dej Loaf exist because historically, that kind of playing into antiblackness was the only thing accepted in mainstream institutions; Stepin Fetchit, an actor who eventually became the richest actor in Hollywood as a result of being typecasted as a shiftless unintelligent black 'sambo' archtype, probably made a lot of jobs for his family and friends too. He did it the only way a racist america would allow him to. It would seem to be misguided to say what he did was fine because it's only entertainment, when entertainment has a noted history of being used as a tool for thought control, especially concerning the black image.
All artform is a reflection of the culture that birthed it. Knowing that, it would seem strange that mainstream black music is the only kind of music (by racial lines) that have such brazen use of the group's racial slurs, for example. Latin-American music isn't full of references to 'spicks' or 'wetbacks', for instance. White american music doesn't have to fill itself with 'crackers' or 'whiteys' to maximize profit. The closest thing they have is use of 'redneck' in country music...and that can't be even compared, in terms of the history of the word or in the frequency of it's use. So why is black music, compared to other music genres by racial lines, so full of internalized racism? It's because that's the culture black americans come from; a culture socially engineered by people who see you as inherent inferiors, the white man. Mainstream rap music is just as much a reflection of american white thought as it is america black thought.
Call me crazy but I don't think that should be defended. It's seems absurd to say 'we need to focus on more important issues' yet seem to take great pride in enjoying and consuming the unfortunate results of these said issues which is what this music is. If you want to listen to this garbage, by all means listen to it. Lords knows I do, as well...but you can't say 'let's focus on ACTUALLY NOURISHING THE COMMUNITY" while also saying 'songs about nourishing the community don't make me dance, songs about community destruction does'. Proud ignorance has gotten us nowhere empirically. We gotta switch to south paw.
