Let's accept for the moment the identification of the Nazis as "right" even though I reject that definition because Hitler was a darling of the progressive set in the western world before our troops started liberating concentration camps. The labeling is largely bullshit because in reality whether you examine Stalin or Hitler you still end up with a corrupt oligarchy achieving wealth and power by completely defiling any concept of individual rights and freedoms with all power to the state and anyone in the way getting steam-rolled. Sometimes literally.
How many US university departments have Nazi instructors in them?
How many have openly communist instructors in them?
If you go to the average college campus, how many Hitler t-shirts will you spot?
How many Che t-shirts will you spot?
How many Nazi organizations successfully recruited people within the government of the United States and in important cultural positions within the United States to advance the Nazi cause?
How many did the KGB successfully recruit in the United States?
In other words, if we accept the proposition that the Nazis were "right wing" then it does not seem to be a terribly successful sell here in the states. Probably because it's rather difficult to ignore the outright criminality of the Nazi regime since we invaded their territory, killed a bunch of them, and captured plenty of evidence of their crimes.
Meanwhile here in the US you can count on Thomas Friedman writing at least two columns a year in our supposed newspaper of record about how awesome the Chinese are because they "get things done", completely glossing over the fact that how they get things done is by killing people. He's the Walter Duranty of our time. And he's even using the exact same verbiage progressive luminaries of the 30's like George Bernard Shaw used about Herr Hitler and Stalin to boot.
And our mainstream press has been giving Castro a rhetorical blowjob while there are still survivors of his concentration camps and prisons alive to tell their tale. Because he's a communist.
If we accept the preposition that there are different flavors of murderous tyranny, it's worth noting that there's only one flavor of it being sold on every street corner in the country. If we were keeping score in the sheer levels of human misery and murder inflicted on the planet, that flavor of murderous tyranny was murderous on levels that make the combined efforts of Hitler, Pinochet, and Franco look like a bunch of pikers.
Very nice summary.
