I've been watching this movement from when it was less than 20k members (not that long ago). I'll say a little about myself. I'm a Navy vet, but I served during the Reagan years before the resent series of Military Actions that stirred up the Middle East.
I've spent most of my adult life as a "Jeffersonian Liberal", and I arrived there through study of History as a hobby, and playing Historical table top games. (pushing around miniature American Civil War, and Napoleonic pewter figurines).
As a Jeffersonian Liberal, I most compare with the Libertarian Party, but I vote the Person not the Party. I'm a Small Government, Fiscal Conservative, Social Liberal. As such, I've never really fit into the typical "Two Party" mold. I've learned the lessons of History though, and believe me when I tell you that as a Species, we have been down this road before. There is no Right Way to Implement Communism. It goes against Human Nature. We are far too selfish, and barely evolved enough to comprehend the consequences of our current reality, let alone attempt to implement a Fantasy Utopia.
I'm out here, on the sidelines watching History being made, and I'm rooting for Love, Civility and Compromise.
