There are dozens and dozens of rappers and hip hopsters. Kanye's goal is to be the most famous. Like Madonna, hw does not want to just take the money and fade away, he craves fame. To do this, he has correctly defined what trait he mu7st possess that others do not: DEFIANCE. This is what has kept Madonna, Mohammad Ali, Elvis, the Rolling Stones, Jack Johnson and even Sinatra in the limelight. He has identified his way of being defiant as jumping on the stage at the Grammys.
You, CU4, and your opinion are of no real concern to Kanye West, as you are not a fan of any hip hop or rapster, and neither am I. He is of course, perceived as an asshole, just as Sinatra was seen as a gangster, Elvis as Po' white trash, Madonna was a slut, the Rolling Stones as hooligans, and Ali and Johnson as thugs: one with a wacko religious cult and the other with a thing for White women.
Since you guys are not all that up on history, I mean THIS Jack Johnson, the "Galveston Giant". Not other Jack Johnsons that are still alive. This one died, unlynched, in 1945.
