The Nazi/Commie name calling has been around forever. I am one of the people who believes there is a difference between Fascism as an economic system and the entire Nazi project, just like there's a difference between Communism as an economic system and Stalinism/Maoism/Juche or what have you. I'm not a fan of either, but I can see the appeal of fascist authoritarianism or communist authoritarianism particularly in nations where the current system seems to be broken. I remain shocked at how well Communism is looked upon by people who should know better, though, and wonder how it's gotten away with its reputation so much less ruined than fascism by its examples in actual practice.

Both systems have such horrible failure modes that, even if one believes them to be good systems if properly established, one should recognize that they shouldn't be attempted. You will inevitably end up with a Hitler or a Kim or a Pol Pot. Fidel Castro is kind of a best case scenario, isn't he? You almost never get a guy like Pinochet who says he will step down, and actually does. And even that will be less likely in the future given how the free world backs out on promises to dictators who agree to give up power.
