That Cappadona story sounds interesting. Other than that, I know that the Government and record lables collaborated to destroy the political aspect and influence in Hip-Hop to dumb it down and saturate it. Its very relevent but then you do have people like Professor Griff from Public Enemy who have "over the wall" theories (they may be true, but hey).
Insane Clown Posse have been known to be the "most hated music group in America" because they don't fit with society's norms (eg. Horrorcore) but yet you had Eminem who came from the same style of music and became accepted by mainstrem America (possibly because he was white, but then signed by Dre,
a very popular producer). Ask any Pop fan or most Hip-Hop (Pop or underground) fans about ICP, don't be surprised to get a negative feedback. It's basically about what you're open to but ICP's fans, who identify themselves as Juggalos/letts (female) usually consider themselves as outcasts from society. They were either bullied in school, did alot of drugs, or were just singled out, but thats the way society perceives them. People would be shocked to hear that a college graduate, nuclear scientist, or police officer may be a Juggalo them self (it could happen, anyone could be one).
To me, Juggalos are ok but there are those who take ICP
WAY TOO FAR!!. If you're at a Psychopathic Records (ICPs label) concert, you may hear the "Whoop, Whoop" call (stolen from the Bloods) or "Family, Family", see people drink Faygo (cheap soda made in Detroit, MI made popular by ICP), wearing clown face paint along with people already on drugs. Even if you mention the words MTV, Kid Rock, or Eminem, Juggalos would be willing to rip you a new one (even though D-12 made up with ICP). Juggalos have their own cultures and beleifs so you can see why some people would think that they're a gang (or a cult in that matter! lmbo).
This trailer for a documentaty on Juggalos is an example of what I'm explaining:
