Thanks, Bunny, for pointing out the obvious -- the most left wing guy on the board revealing his complete ignorance of history. I've said it before -- every significant dictatorship in the last 100 years has come from the left.
The reason is simple. Political models range between two poles. On the right side, there is belief in the individual. At its extreme end, for example, would be anarchy where there are no rules whatsoever. On the left is belief in the State. At its extreme end is totalitarianism. The farther left you go, the more rules are imposed on the individual for the benefit of the state.
This is why you see an increasing intolerance for free speech and self-protection as you move toward the left. Such things are anathema to leftists. It's all about limiting the individual in order to shore up the State. This fear and distrust of individuals is what invariably leads far-left governments to do things like round up political dissidents, control the media, nationalize private property, build walls to keep people in, etc.
