I wish people would realize libertarians are NOT liberals. Linertarians want small government and personal liberty. That means, unlike liberals, libertarians don't think its government's job to "rob from the rich and give it to the poor". They aren't so much socially liberal as they are conservative about liberty and refusing to regulate one group's morality on another group.
If so many U.S. citizens weren't tools of the two party system, they would realize just how libertarian (or constitutional or some other philosophy) they really are.
