Time for me to stick in my two cents. First of all, I think there is no right or wrong here, word definitions are a matter of opinion. My personal opinion is that all of you are partially correct. All the words apply. Hitler's regime was authoritarian, totalitarian, and fascist. This matter is a good illustration of the folly of trying to state what the facts are, rather than stating what sources say. If you would quote sources, then everybody is more likely to agree on the fact that the sources say what they say. The article is supposed to be reporting what major scholars think, not what editors think.
