Why do you think he isn't? What has MJ done to prove he isn't? The majority of blacks in this country have been convinced by the Left that they are victims of racism by the whites. They think the Democrats are their friends and the Republicans are slave masters. In reality, the blacks have been enslaved and controlled by the Democrat Party since before the Civil War. Many blacks think Abraham Lincoln was a Democrat!
They believe the Democrats are their friends of blacks who will exact revenge on the evil whites that practice a modern version of slavery in 2014. That's what MJ believes and why he champions POTUS Barry Soetoro Obama.
