To be fair, “Jar Jar is his favorite character” is a huge mischaracterization of what he actually said on the writer’s part. In the video the exchange actually goes like this:

Interviewer: “If you could be any Star Wars character, who would you be?”
George: (clearly exasperated) “I don’t know. I like all the characters. Jar Jar Binks.”

He goes on to get himself all flustered about how much he hates being criticized and it’s really cringe-y. Completely aside from the franchise, I think it’ll probably good for his mental health to be out of the public eye.
