Again, your understanding of libertarianism is also based on msm popular babble or what you hear people claim as opposed to study of the actually authors of that movement. It begins and ends with the non-aggression doctrine—PERIOD!
But it is getting balled up with the tea party message, which isn't pure libertarianism.
And to suggest the meanings of words and labels don't change is silly. Do you honestly think that 1850's Republican party is essentially the same at it's core as the 2000 version?
