Really?? I thought the Nazi's and the Ruskies were from the same cloth?? They both killed millions and they were both socialist. I don't really understand all this left versus right stuff. The Nazi's were by definition a national socialist party (left). The USSR and Mao's China were also left. The USSA will of course be left.
Infidelz.
You need to read more. A socialist government nationalizes industries, at the extreme end such as the Soviet Union, all national industries. Nazi Germany did not do that and cracked down hard on workers rights. It doesn't matter what they call themselves, all that matters is what they do. I know some right wingers try to pass them off as leftist, but that absurdity doesn't pass even a cursory examination. A really (really, really) crude way of looking at it is this: in a fascist nation the businesses own the government and in a extreme socialist government the government own the businesses. In both cases there is an unhealthy marriage of government and business, but who is the dominant and who is the submissive varies.
The basic truism here is that totalitarian nations are a bad thing and it doesn't matter if they are rightist or leftist, it is the totalitarian part.
