When Kanye West stood on NBC four years ago and said "George Bush doesn't care about black people," I applauded. When he acted a fool on stage after not receiving some award he deserved, I laughed. When he came out with that really weird CD after dealing with personal crises involving the loss of his mother and break up with his fiance, I sincerely felt for him (but never bought the album).

But after Kanye's stunt Sunday night on the MTV Video Music Awards, I wanted to slap him. Damn brother, that was just pathetic. When Beyonce told you she liked men with big egos, you surely put that theory to the test.

Kanye West's decision to bum rush the stage and yank the mike out of the hand of Taylor Swift, a 19-year old woman winning her first award has finally certified him as the jackass that everyone thought he might be. I have been a big supporter of West, and I still support him to a point. He brings some degree of intelligence to hip hop that the industry has needed for a long time. But the truth is that his actions last night were rooted in extreme selfishness and horribly arrogant behavior. Not good for Kanye, nor anyone else.

This must have been "The weekend the black folks went wild," because Serena Williams had an equally problematic outburst at the US Open. After a very bad call by one of the judges, Serena felt the need to offer to shove the ball down the "f*cking throat" of the woman for making her mistake. OK sistuh-girl, does the judge really need to have the ball shoved down her throat?

Serena's outburst didn't sicken me to the same extent as that of Kanye. Serena was in an incredibly tense situation, right at the end of a very important tournament and the judge made an incorrect call that could have cost her a major win. I sincerely felt for Serena, and I can't say that I would have risen above the temptation to offer the judge a tennis ball for lunch myself. But Serena must also be aware that there is going to be a huge financial cost to pay in terms of endorsements, suspensions and money lost from the US Open itself.

Kanye's tirade seems to be a publicity stunt gone bad. He is likely to lose money from his white fans, since there is the practical reality that many interpreted his actions as a black man assaulting a defenseless white woman. But let's be real: If Garth Brooks were to roll up on stage and yank an award out of Beyonce's hands, Malcolm X and Martin Luther King would rise from the grave for the inevitable entertainment race war. Oh yeah, Taylor Swift is also a country music "saynger," so I'm sure that the hillbillies have their guns cocked right now.

Serena has to simply keep her composure. She's not just an athlete, but a corporate brand and role model. Companies are not going to be interested in signing an athlete who appears to be unpredictable in her behavior. Also, while many of us can understand her choice of words, the truth is that the rest of the country does not. Most black women are creatures of class and dignity, and some wonder if Serena did a good job of carrying the torch. At the same time, black people are as heterogeneous as anyone else, so Serena does not represent every black woman in America.

I still love Serena and Venus Williams to death. Kanye's my boy, but he needs to go ahead and get that therapy. The world will soon grow impatient with Kanye and these outbursts are going to kill his short-lived career.
