There are those now who are saying, "American Socialism didn't fail because it wasn't /really/ Socialism." I'm answering, sorry, you had your chance. You can argue on blogs all you want. The experiment has failed miserably.
Point being, simply asserting a preferred definition is not a compelling argument. Whatever it was that was going on, it hasn't been working. Making one or another particular economic philosophy the bogeyman isn't going to help, however good it makes people feel to be able to say, "I told you so."
