Also, to call the US socialist is hilarious. Tell me more funny and false things.
Here, I think you're right. the US is a very
socialized country, but not
socialist. If it fits any -ism, it's Fascism.
Authoritarian? Check.
Nationalistic? Check.
Socially Darwinist? Hmm. Not so much. Check back in ten years, though.
Socially interventionist? Check.
Militaristic? Check.
Corporatistic? Check. (I know that's not precisely the word but you all know what I mean, Government and Corporations working hand-in-hand.)
5 out of 6, and the only point where it fails is the massive social programs the US offers for the 'lower classes' instead of the eugenics and euthanasia of WWII-era Italy and Germany. As I said, though, give it time, once that social health care starts racking up the costs of old age and poor diet, see if some Social Darwinism doesn't start popping up in national policy.
All these conditions that you've laid forth are necessary conditions, but not all-in-all sufficient for a fascist state-- there's something missing, because most governments/nations would be considered these, but we acknowledge very few states as fascist states.
The US isn't a fascist state, not yet. I think the second we single out an "other" that is irreducible, and we don't extend proper citizenship to is the second we become a fascist state-- irrational persecution of "other"(s) is probably what sets us apart from fascism.
