Your comments are rather confusing because Communism as practised pretty much in any country calling itself such was an overarching totalitarian system incorporating not only a command economy, but a command media, command philosophy, cult of personality, and command arts & sciences staffed from a command educational system.

Yes. If you look at it in terms of countries that have called themselves communist. But if you think in terms of a country that considers itself a democracy, but one in which communism is practiced, you get a whole different perspective. I'm guessing that there are no examples of a democratic country that practices communism so far. I'm guessing that there are people (Ms. Sgrena possibly being one of them) who believe that it is still possible, and would like to help nurture such a political and economic environment.
