I mean I kinda thought of Hitler and him being a cake-eating vegetarian and then had to improvise afterwards. I did try to pedal back a bit and say "or one of his generals".
Oh and it wasn't just Nazis who denied the holocaust back then. There was an IIRC French historian I can't recall the name who went in there not believing such a thing possible, then saw concentration camps with his own eyes, and went on to compile a minimum number, with the intent that if you say a lower one, you're definitely denying because the number is unassailable, as a minimum (but probably higher. Most definitely probably higher, in fact). Threw out e.g. SS reports because they could be claimed to be fabricated to get a promotion and shit.
