I've never been sure what
>the point is that people are trying to make with this.

Me neither. Of more relevance is that Hitler was a junkie and he liked
cocaine as well.
He could have had celiac disease as he was particularly short, was
irritable and had low self esteem. All these are symptoms of gluten
intolerance. He should have been eating meat because celiacs do better on a
high protein diet. Vegetarians frequently eat a lot of grains for protein.

All the best,
