Well, I know the term "libertarian" has a wide sense. I must be clear that when I use this word, I of course talk about people who sympathise with the idea of laissez-faire capitalism, limitation of goverment's prerogatives and personal freedom. So, Ron Paul is indeed a libertarian, but I'm not talking about people like you or Chomsky who, ultimately, are socialist for me. I'm also talking about objectivists since thay defand capitalistm and individuals freeedom too.
By the way, many objectivists are not randist.
