Oh, please. Name me one time in history when a leftist has used the power of the state to kill political opponents... Other than Russia, China, Hitler's Germany, North Korea, Vietnam, Laos..., you'd be hard pressed to come up with even 100,000,000 examples. That is hard even statistically significant for a Leftist...
Yeah, it happened every time in every place in which collectivists gained the power to do it,
but we here in America, we’re different, it wouldn’t happen here.
This is the viewpoint of those that refuse to recognize the Biblical truth of the fallen nature of Man. They believe that because they live now and are so much more perfected (evolved?) than anyone in the past, that they can take power without genocide.
