While I agree that P is being a jackhole and that his whole "I-am-allegedly-doing-this-for-the-Katrina-survivors-but-refuse-to-actually-put-myself-out-there-and-try" schtick is a little lame, I disagree that his continued existence on the show is due to all the ghetto-dwelling, rap lovers who apparently make up a significant part of the viewing audience. (Yeah, right.)
That makes no sense.
First, if you like rap, you probably are not a fan of Master P. He raps about as well as he ballroom dances. I am orginally from New Orleans, my sister was one of his back-up dancers, and we all thought he was a living, breathing offense against music.
Second, if you are from the ghetto, then you are from the ghetto. Nothing else logically follows from that as to how you would vote or whether you would even watch D-list stars attempt to ballroom dance.
Just because P purports to appeal to a certain demographic doesn't mean that he actually does. And just because you happen to urban, poor, or ethnic doesn't mean you will vote blindly for someone without regard to their skill level or attitude. I mean, some people might, but enought to affect the results? Unlikely.
So, my thought is that if there is any "discrimination" going on, it is from the people who assume that the sole reason P didn't get booted is because "those people," (i.e., the poor, black, and urban) are racist, tastless, and ignorant.
They are many reasons why P might still be around. For example: (1) pity votes, (2) Katrina-related sympathy, (3) comic relief, (4) entertainment value, or (5) support from P/Romeo fans. Or a combination all of the above that creates a perfect storm suckitude that allows individually reasonable people to make collectively bad decisions.
