Gotta shake my head if this is what it takes to make him think things over.
I hear what you are saying, but you gotta hit 'em where it hurts, man...
A person shouting racist things is never going to be shook by the condemnation of people they have preemptively disregarded (if anything, it will confirm their suspicions that the world is overly sensitive). Moreover, he hasn't been condemned (at least not publicly) by any of his friends in the industry; so it doesn't look like he is receiving any pressure from that side of his life. Lastly, he has been praise by the type of people he seems to associate with politically. When you consider the bubble people like him operate in, I wouldn't be surprised if he sees himself as some kind of hero now. That is certainly how a specific type of person has received him.
However, this is one repercussion I think it would be hard for him to spin. This is Jon being removed from a project that means something to him.
Yikes, man. Fuckin'... yikes.
