Actually in most cases libertarianism is simply the position of arguing that the Government is causing whatever problem happens to be being discussed at the time. Unfortunately the idea of libertarianism isn't against regulation is a bit of a fantasy, because no matter what, someone can and will take the more extreme position against regulation and this person will be seen as more libertarian. I think ideologies are in general are flawed in their ability to be more easily defended if taken to the extreme.

On the whole, the Founding Fathers were extremists for liberty. They were quite radical, by the standard of their day and certainly by today's standards.
Extreme liberty == Articles of Confederation (the first failed U.S. government, wasn't strong enough) versus extreme national socialism == 10s of millions dead.
