The American statist religion seems to have two branches, both of which coalesced in the mad “progressive” Wilsonian rush into WWI: America as a “Christian” nation with a duty to “save” the world with “democracy”. Read 8 pages of “The War for Righteousness” by Richard Gamble. The declaration of war was passed on Good Friday, 1917 and that was not a coincidence.
Since then, the Democrat “progressives” have dumped the “God” part of the religion, while the Neocons have adopted a strange “dispensationalist” version where “Christians” and the USA have a duty to help Israel steal more land and induce WWIII and the “rapture”. (I have had the recent unforturnate experience of debating an entire army of Mark Levin types who “like” genocide of the Palestinians). The Neocons actually seem to believe that Obama is a liberal peacenik who simpathizes with radical Islam. They think libertarians do too, while the left “progressives” think we hate everyone (and left "progressives" sure HATE us). Both sides seem to think the US government has magical powers to cure things, but they disagree about what those magic powers are and to whom and how they should be applied. Each side insists that folks who disagree are evil and/or stupid.
Both sides are still gung-ho about imposing their religion upon everyone else and the rest of the world. When their endeavors blow up in their faces, it’s because the opposing “progressive” side (left or Neocon) just didn’t do it right.
I suspect this is the real reason why we have such trouble even defining basic terms with the statists. This would also explain the instantaneous success of Keynesianism. Even more troubling is the realization that with this statist religion being fundamental to the statist belief system, the statist is not going to be in the mood to hear that his life's work has been for naught. And he's really not going to be in the mood to hear that he and his belief system are basically the worst problems facing mankind.
