He didn't do a Nazi sign, he waved. He didn't endorse a "far right" Nazi party unless you're saying a quarter of the German population are secretly Nazis? They're right wing but they're not "far right".

He didn't say Hitler did nothing or that he wasn't responsible for the Holocaust. He made the very good point that one man can't do that amount of damage alone, and it relied on the power of a centralised state with excellent record keeping. There is a reason modern European states don't even collect this data! States are dangerous.

Your view is insanely warped. I don't know why.
