Unfortunately, Libertarians are right, and so are libertarians. Capital "L" Libertarians are the political ones, who want much of the same things that the Dems and Reps want.
The small "l" libertarians want no real political activity at all. They fight because they are ignorantly unaware that the 6th, 7th, and 9th Amendments render government ineffective... if the people want to neutralize government, individually, at any time... or in joint, simply by using the amendments to neutralize government.
Both of them are right about the other, and both of them are wrong, at the same time. And it is born out of ignorance.
Google and Youtube search "Karl Lentz" and "Bill Thornton" and "Richard Cornforth" for practical info along these lines.
