If there really was some kind of Turner Diaries style race war, blacks, even the gun toting ones, would get annihilated so thoroughly by every last gun toting redneck it wouldn't even be funny.
It's in black America's best interest to suck up a little bit to whitey, not the hostility and hate, they've been doing exactly the wrong thing for years at this point.
EDIT: to expound on this thought a bit, what's work's best for black America is an underdog status, that's what made the "white power" types in the old days seem like obnoxious jerkoffs because it seemed like they wanted to kick people when they were down.
But now, after the first black President, when 100% of modern media has token black characters no matter the context and maybe 80% of modern media is just outright "black" and when you're walking around with assault rifles, bullying people on social media, bullying people in general and causing such wanton destruction, your underdog status is gone, it's white people who are the new underdogs.
