I think what this thread is more concerned with is more concerned with is libertarianism, rather than anarchism. Minarchism, which has been mentioned, is generally considered to be the most extreme form of libertarianism. Unfortunately, in the Australian political environment the position of libertarians (and there are few of them) is largely misunderstood. Some people seem to classify them as superconservatives and others understand them as a strange type of liberal. In fact libertarianism is entirely removed from this mystical, ridiculous spectrum. And this is the reason that there are so few 'anarchists'. Most people are brought up understanding everything from a Liberal/Labour, Conservative/Liberal dichotomy. Contemplating any other sort of political ideology would send their little minds into overdrive.
On another note, does the person who believes themself to be an 'Objectivist' mean an Ayn Rand type of Objectivist or merely someone who disputes subjectivism?
