Similarly he felt his TV show was cancelled after two seasons because it wasn't PC, but his show wasn't getting good viewership and had a terrible time slot. That's a pretty typical trajectory for a TV show, it's like complaining your startup failed.
He wrote a lot about explicitly magical thinking. Sort of along the lines of The Secret; that he could achieve things where the odds were against him through sheer force of will and wishing. That's not necessarily a problem but it does set you up for denial when things don't always go your way. And the denial is dangerous.
The later chapters of his life were marked by tragedy. His stepson died of overdose. His marriage collapsed. He lost the ability to speak and had to fight like hell to get a proper diagnosis and treatment (he later recovered). He went through COVID like the rest of us. Unfortunately these events would seem to have hardened and radicalized him.
I think we can understand and empathize with that without condoning it. I hope he found his peace in the end.
