Ok, he's a racist.
However that doesn't negate that I can't fathom that a public figure, a guy who's constantly in the spotlight would create such a shitstorm without ulterior motives.
He could just keep his mouth shut and be the "nice little screaming Felix" like he always was before he started changing his direction.
You're still babying him. In the stream labelled 2 and 3 in the OP, he lays it out quite clearly. He says that he knows that no one watching the stream cares. What does that mean? It means that he thinks that he doesn't think he'll be affected when he does things like this.
We know how sincere he is about his apologies - I'd link the joke he made about Charlottesville if he hadn't deleted the tweet since the last thread, a joke about the same Charlottesville riot that he claimed made him realize that Nazis were a real thing and that he should care about the jokes he makes. He's been flagrant in showing how unapologetic he was for his Nazi jokes, and it's for the same reason.
So it's not surprisingly that he specifically says in his apology that it's not that he thinks he can get away with anything. He believes that his fake apology will satisfy the people who don't watch his videos and take the attention off, which will leave him free to continue his behaviour where only the fans are watching because the fans don't care.
