instead of attacking ideas, influence with facts and knowledge, like nitro did with his charts, that was really all that needed to be said, except that, of course, the mafia had no hand in creating the bloods and the crips, the crips was first intended to be a more positive than many would think, crip stands for something like community R improvement P, lol i forgot but you get what im sayin, then the bloods was formed after the crips from smaller gangs that banded together to have enuff numbers to stand against the crips. these two gangs really just had turf, shit didnt really start gettin bloody until crack hit the streets, then they killed each other by the hundreds.
and on the issue of who created rock and roll? everyone had a part in creating it, leave it alone because theres no proof of any "one" creating shit, People created it, Talented people, leave it at that.
