…and Hitler wasn’t a vegetarian as we think of it. He mostly ate horrible vegetable slop (while being injected with all sorts of crap taken from livestock) but not entirely. He certainly had no ethical nor environmental concerns about meat.
EDIT
This is not to suggest that food is horrible slop without the addition of meat, just that from what I read his diet in Blitzed by Norman Ohler, was awful slop. Usually mouldy in the bunker too.
