People don't seem to remember that Russia, China, and Vietnam fought bloody civil wars against the Communists. They were not all a bunch of unarmed helpless citizens. The Venezuelan fought Chavez in the streets, and even staged a coup; they lost. The Confederate States were better organized than any Tea Partiers today. They controlled a conterminous block of entire states. A sizable bunch of experienced military leaders defected to them. They claimed to have the 3rd largest economy in the world. They lost too.
One thing the Left knows how to do: Wage total war and kill people. They will not hesitate to turn the full might of the govt. loose on any uprising, but first, they will target all the leaders.
