There's a world of difference between the "big-L" Libertarian Party and a "small-l" libertarian.
For example, most historians agree that Thomas Jefferson would properly be described as a libertarian -- that is a "classic liberal". But I'm quite sure he'd take issue with much of the Libertarian Party platform.
(Damned Liberals misappropriated the word. They're actually leftists, socialists, and communists. And nuts.)
A "libertarian" is not the same thing a "classic liberal".
"Classical liberalism" is the term used to designate the ideology advocating private property, an unhampered market economy, the rule of law, constitutional guarantees of freedom of religion and of the press, and international peace based on free trade.(Mises website)
"Libertarianism is a political philosophy that upholds liberty as its principal objective. Libertarians seek to maximize autonomy and freedom of choice, emphasizing political freedom, voluntary association and the primacy of individual judgement."(wiki)
My issues with libertarians is their primacy of individual judgement...
If Jefferson was as you say, a "libertarian' they would still be hashing out the Constitution...
This country is chock full of idiots that think their rights end at the tip of your nose...letting individuals decide drugs and deviant sexual behavior as normal and within their rights as it's their "primary individual judgment"
Forgetting about the cost to our culture and society as a whole...
Thats why we have a representative type government or are supposed to have one...to give voice to reason and general consensus...not "primary individual judgment"
That is a lie, most historians do not describe Jefferson as a “libertarian” something which didn’t even exist at the time, the European left had not started it yet.
