First proof is not dietary but similar treatment of Gentiles. Hitler murdered millions of Christian Slavs in Europe and so did the Talmudic Jews in Communist Russia.
So if supposedly you are what you eat, then both are tyrannical pigs - see Orwell's animal farm.
See second article below.
"Hitler also ate ham. So if you encounter anyone bragging about loving bacon, that was also one of Hitler's favorites. Adolf Hitler loved and ate bacon. He also ate poultry. Hitler ate squib which is a type of bird, like a chicken or pigeon. So if you have a person who loves chicken wings, poultry, loves hunting pheasants, grouse, etc, you can let them know that Hitler also loved it. Hitler admits eating sausages, killing turtle meat and eating it, and pork from boars and swine pigs. Hitler was a meat-eater."
HITLER ATE MEAT - PROOF - ADOLF HITLER WAS NOT A VEGETARIAN - NOT VEGAN - Hitler and the Nazis were Omnivores
HITLER ATE BAVARIAN SAUSAGES. BACON. PORK. POULTRY
NOW PROVEN HITLER CRAVED & ATE VOLUMES OF ANIMAL MEAT.
IT TURNS OUT THAT ALL 19 OF THE ISLAMIC MUSLIM TERORISTS THAT HURT AMERICA AND PEOPLE FROM AROUND THE WHOLE WORLD WERE MEAT-EATERS. THE OMNIVORES WHO HIT THE WORLD TRADE CENTER AND KILLED THOUSANDS OF HUMAN LIVES ALL ATE MEAT.
