I Was a Card-Carrying Libertarian: Confessions of a Black Sheep Republican
It seems as if the only aspect of Libertarianism you disagree with is their foreign policy of non-intervention. Such thinking is not really “Libertarian” and more nativist and isolationist. There are Libertarian movements (most notably Ayn Rand’s semi-serious movements) which actually argue strongly in favor of military intervention (they wasted no time calling for nuclear weapons).
Such a view is of course in an absolute minority, but it shows that it is possible to be a Libertarian, believing in things like the free market and free trade without being opposed to intervention.
Additionally, Ron Paul does not strike me as a real Libertarian as much as he does as a nativist who “discovered” the constitution. His desire to build a wall between the USA and Mexico to stop immigration stands against principles of open immigration, and his desire to want to pull out of the WTO, an organization which is designed to increase free trade, seems not to match his supposed “Free Trade” ideals.
