I think that all significant meanings of the term need to be covered. I think that the linked article is sort of a rant and completely misunderstands the main forms of US libertarianism (which is basically "less government" and everything that arises from that) by mistakenly defining what arises from "less government" as being core tenets. But that is a sidebar; I think that all significant meanings of the term should be covered.    The article has been somewhat chaotic lately but most folks here are either committed to or OK with the latter.  North8000
