So, I just read the manifesto on the canadian libertarian party's page, and on the US one. The US one is much more what I think of when I hear libertarian, and much less, um, extremist.

Here's what they say:

What is a Libertarian?



Libertarians believe that you have the right to live your life as you wish, without the government interfering -- as long as you don’t violate the rights of others. Politically, this means Libertarians favor rolling back the size and cost of government, and eliminating laws that stifle the economy and control people’s personal choices.



Are Libertarians liberal or conservative?



Libertarians are neither. Unlike liberals or conservatives, Libertarians advocate a high degree of both personal and economic liberty. For example, Libertarians agree with conservatives about freedom in economic matters, so we're in favor of lowering taxes, slashing bureaucratic regulation of business, and charitable -- rather than government -- welfare. But Libertarians also agree with liberals on personal tolerance, so we're in favor of people’s right to choose their own personal habits and lifestyles.



In a sense, Libertarians “borrow” from both sides to come up with a logical and consistent whole -- but without the exceptions and broken promises of Republican and Democratic politicians. That's why we call ourselves the Party of Principle.
