The idea that there is even a true right or left wing is an illusion, feel do I. People either have something broken in their head and want the government to run their lives... or they reject that ideology. It's kinda like trying to find that one "normal" person out there, its just a statistical anomaly.
Why some libertarians have this deep seated 'need' to distance themselves from "right-wing" is beyond the understanding of mine. Politics is two dimensions instead of one. In addition, remember the axiom: 'That you become what you hate'.
