Several responses on here I agree with, many that are horribly misguided. I'll refrain from either cosigning or flaming though and steer this in a different direction.
My man's dp (POEM-CEES) put it like this: "it's one of those things where nas said some dumb shit with confidence and black thought said some relatively reasonable shit in a somewhat unfocused fashion."
Thing dead.
Unless...
Nas tries to respond again, then it'll get ignorant. Or, Black Thought came with a rambling response to bait Nas into attacking again so the Roots would have an excuse to come with the brutal retort. What a silly conspiracy theory! Can't wait for zealots to lap it up! Ha.
Always doing my part to keep "fake rappers" out of "our hip-hop community"...
