@everetra - I don’t know the answer to your question, but I do know these terms evolve over time. For example, political left wing advocates—liberals, by the old lexicon—now have come to refer to themselves as progressives. It’s a pretty relative distinction. I suppose liberals would object to right wing activists calling themselves “Constitutional conservatives”—as if the left doesn’t care about the Constitution.
I honestly don’t care about these milder euphemisms, I just don’t like it when either side starts bashing the other and throwing words like “fascist,” “socialist,” “communist” around. I don’t think there’s a place for this kind of language in civil discourse.
