It is commonly believed that Adolf Hitler was a vegetarian. Sometimes that is used as some sort of argument-by-association that vegetarianism is a bad idea:
For example, "Vegetarians Are Evil" web-site:
Adolph (sic) Hitler would have been a model PETA activist. Adolph Hitler was a vegetarian - although it is widely known that in his early years he would have a lapse and indulge in the odd liver dumpling.
There are some, especially vegetarians, who claim this is not true.
For example, Michael Bluejay:
For Hitler, there's no compelling evidence that he stuck with a real veggie diet for any appreciable length of time. Multiple sources document him as eating meat throughout the 1930's.
Is there any evidence for Hitler's vegetarianism? If so, was is there any indication as to the motivation and extent of Hitler's vegetarianism?
(Of course, I do not mean to indicate that Hitler being or not being a vegetarian would be an argument relevant to modern vegetarianism.)
