Hey, it's going to be ok.
I recently did the same and blocked my father for similar reasons just before Trump was elected.
The rage will stay with you though, it's best to talk to someone about it. You're always going to wish he was better and resent that he's become a disappointment to you. He lives rent free in my head and I just stay angry at how miserable of a disappointment and how much of a hypocrite he really is.
The truth is, your father was always like this, just like mine was. I just never wanted to admit it.
I don't have any answers for you, I'm still struggling with this myself and it eats me up inside every day. All I have is solidarity. There's a lot of us out there. Hang in there, you made the right call, you're on the right side of history. He isn't. You can't convince him otherwise. This is what people like them do, they dig in.
Best of luck, I hope you figure out how to stop thinking about him for the next few years.
