I don't think people are saying you should never make a single joke about the holocaust. I personally can't think of any funny holocaust jokes I've ever heard, but people are free to joke about whatever. They just aren't free from public reaction and consequences. Should anyone be jailed for jokes? Of course not. But can they be socially ostracized and fired? Yes. I don't get why people are so desperate to make everyone accept his "jokes" - if you can even call them that. Like I said, I don't see how "Hitler did nothing wrong" and "Death to all Jews" are jokes. They seem more like statements.
