Xanthippa has posted a five part series of videos that neatly explain key concepts (and misconceptions) relating the various political philosophies - individualism vs collectivism, right vs left, rights, liberty, anarchy, socialsim, communism, fascism, Naziism, etc. The series is topped off with a presentation by John Robson on the Magna Carta. Excellent.
Dedicated libertarians know this stuff inside out and do a great job of explaining it. But what they haven't been able to do very successfully is to get a sufficiently large following to attain political power based on libertarian principles. The Libertarian Party has been unable to do even what the Green Party has done. Not even close. Canucks are too well indoctrinated, from birth to death, in collectivism. As the videos warn: "The evidence presented here was not part of your education". All that "greedy", "selfish", "uncaring", libertarian individualism is just too scary. Though it could be argued that the libertarian philosophy does enjoy some measure of representation within the Conservative Party. Maybe that's the most they can reasonably expect for now.
