Because that is what the media wanted you to think. Kevin Spacey always had little positive callouts all throughout the (pedophile-infested) media, while Tyson was always labeled "violent", "crazy", "stupid", or some other form of "deplorable".

I mean, heck, just look at Kanye West. There were several old memes that tried to label him as a dumb, narcissistic, selfish Hollywood elite (the "interrupting Taylor Swift's award ceremony to say Beyonce was better" video and copypasta, the "Gay Fish" episode of South Park, most of the music videos for his songs, etc.). But instead of being a whiny little political elite like most of Hollywood in 2016, he kept pretty quiet until after Trump was elected, when he actually stopped mid-concert and just ranted some red pills into his audience's ears about the evils of Hillary and the modern media compared to the possible good times under Trump. After that, the Hollywood elites around him had him locked up in a mental asylum for weeks, until he stopped being publicly pro-Trump.

I have a feeling that a lot of the talented black people who were abused or forced to play stereotypes are going to come out and show their true selves in the next few years, while those who were entirely pushed to the top for their looks or their anti-white hysteria are going to be exposed for being some of the actual biggest Hollywood idiots and racists.
