He's caught in the middle of having to feel the pressure to take a stance against something that has nothing to do with him or anyone he loves and that many of those same people around him are for.He also said he was "caught in the middle" when PewDiePie said "n*gger." Like what is there for him to be caught in the middle of?
This guy probably has a lot of racist friends and associates. He's also probably not racist himself but would rather not have to weigh in on race related issues. In his personal life none of that stuff has anything to do with him.
Such is the price of internet fame. People expect you to be a decent human being so you end up giving takes on stuff you'd never have to in your personal life.
Like I said the guy is a coward. This is a man that doesn't believe in taking a principled stand for something even if it doesn't directly effect him.
