Stone is not incorrect in his statement. Hitler is VERY overused because he decided upon a course of action that most of the world does not agree with. If you look, however, in the history books of two very different nations there will be many people that the majority of the country considers a horrible person much like or exceding Hitler. Hitler is only used due to the fact that he is recognized by the entire world for what he did. Hitler was a visionary. Granted, his vision was not only impossible but also considered totally wrong by most cultures. But this does not change the fact that he is one of the greatest leaders in history and an extremely intelligent man. Many people could be considered worse than Hitler. He is nothing but a familiar symbol.
Also, please do not flame me for crediting Hitler. I do not admire him or such foolish thing i merely view the point without bias.
