"Beans can't have protein. That doesn't make any sense. Protein is what meat has."

I have spoken to two different people with no connection between them who thought that beans had no carbs and no protein, they were "different," because carbs were grain things and protein was meat. I wouldn't normally judge people for ignorance, but both of those people used the terms "carb" and "protein" while expressing extensive and very strongly held beliefs about nutrition. They are not much different from anti-vaxxers in my book.
