The real difficulty is that tough-talking lefties make very poor soldiers. Acts of random destruction are fine as long as they have a nice warm apartment to go back to, to listen to Rage Against The Machine afterwards, but the passion of the Left does not make up for its total lack of self-discipline (the two are not unrelated). A glance at Orwell's Homage to Catalonia, just about half-way through, gives us an idea of what happens when the passion runs out and reality sets in. It isn't pretty, and by then the espresso stands are all shut down and the beer no longer gets delivered to the revolutionary cafes.
To a great degree there was a visceral realization of this East-West dichotomy in the form of one Sarah Palin, whose image of triumph over a blood-soaked caribou evoked horror and revulsion throughout the ranks of the urban enlightened. These are accustomed to hiring their killing done for them whether it be man or beast. It is they who regard soldiers as hirelings and mercenaries. And they are very unaccustomed to hearing the word "No."
The notion of a Keystone Cop group of sad-sacks exerting their political will on the community works only if they are the only ones with guns. I do not anticipate many Revolutionary Cadre detachments setting up shop in western cities, not for long at any rate. In small towns, not for much after dark. In the countryside they'd just...disappear. And there's an awful lot of countryside to control. Just my $0.02.
I've got an old Montana homestead that's probably never had a human set foot in some places.
Molon labe, mutha. LOL
