I'm sorry, but you are playing with words. A muddy style and a self-contradicting argument are not the same thing as a broad overview. Read Shirer on Nazism or (if you cand find it) Kolnai on the Nazi ideology: those are broad overviews. Shooting oneself in the foot because you have gone too far with an unsupportable point and you have to make some sort of obeisance to facts does not count.
