What makes it entertaining for me is that he built up his brand, at least in part, by being an obnoxious jerk to others. Even that might have worn off by now, but his determination to dig in and keep pushing a script where he is the downtrodden hero and everyone else is the malicious villain keeps things fresh and interesting. I'll give him credit, he's always been very, very good at bringing attention to himself.
Of course, now he's unhappy with the attention is getting, but that's just how it goes. Be a shitty person, win shitty prizes. Or something like that. Can't wait for his next foot-in-mouth moment!
