People compared Bush to Hitler and got away with it. I feel no sympathy for anyone who thinks Gingrich is extreme and if you look at the democrats today there really isn't much different between them and the communists from Russia in the mid 20th century. The nazis? I won't go that far but running Government Motors while it's still somewhat owned privately is a good start down that direction.
Do you actually believe all that???
Really, I consider myself to be a socialist and that anyone could mix up two ideologies as radically opposed as liberalism and socialism (or liberalism and fascism for that matter) is beyond me.
If someone who actually completed highschool would make such a comparison, it would be worrying enough. But when one of the most important spokesmen of the main opposition party in the most powerfull nation on earth starts to sell this kind of crap, it's just plain sickening and/or incredibly cynic.
