I was a member of a political forum that was slowly taken over by communists, socialists, and some other real loons. There's people out there who celebrate 9-11, and I mean educated professionals from affluent backgrounds, not street rabble. There's people who praise Stalin and Kim Jong Il, incredible as that may seem. There's people who will tell you that Stalin's purges were a capitalist fabrication, that the Winter War against the Finns was justified, that you're a "colonialist butcher" if you think otherwise. Ironic wording, since the USSR was nothing more than the Russian Empire dressed up in communist rhetoric. A lot of these fools live in countries that were protected by America's might for the half century of the Cold War.
There's no point debating people like that.
