This terminology all being ass backwards when compared to the rest of the world is unique to the USA. I am not sure what the roots of that are but that Orwellian use of language goes right back to the Countries founding (All men are created equal in a Country where slavery was extant).
Neoliberals like we have here in Canada are often labeled as Marxists or Socialists in the USA , this along with that hijacking of Libertarian as a term to apply to a US Version that is nothing like the European one.
It all very strange but it occurred to me one day that people can not really help it when they are born in a system where the use of words and language has very different meaning then in another land and when that language so distorted it very much harder to communicate ideas.
I mentioned a program I heard on the CBC about Americans that had moved to canada 10+ years ago (during the Bush years) and what they found different about Canada then the USA. One guy called in to talk guns indicating he always owned a gun in the USA yet was always afraid. he said he was afraid every time he met a stranger or was on the road or went to a store. He mentioned that one day he woke up in Canada (where he did not have a gun) and realized he was not living in fear anymore. This speaks to how people think and act differently when they are raised in a given environment and how their perceptions of the world are shaped by the same.
