The extreme extension of conservatism goes through libertarianism and continues on to American Mountain men. The extreme extension for the American right is no state, not a hyper state of any kind.
Your confusion is in looking at the political world as a single line that goes from one extreme to the other. It is not. There are a multitude of paths (monarchist, fascist, tribal, communist, socialist, theological, and a plethora of other utopian schemes) that all end in total state control when taken to their extreme.
Running personal liberty to its extreme does not result in a larger more powerful state, it results in the absence of a state. The only reason that the NAZIs got tagged as being on the “right” is because they were attack Soviet Russia and it served the purposes of the American Left.
Hard to tell what you're basing your assumptions on about what I'm saying. I never said anything about a straight line - far from it. You're not addressing the points and examples I made about the nonsensical and illogical nature of extremism (like how "love and peace" turns into tyranny). You're example of mountain men may be one branch of right wing extremism. You haven't addressed the question why today's Nazis and Skin Heads ID themselves as another branch of right wing extremists.
It's a interesting subject to me but no big deal. The theory is that at some point the extremes on both the left and right bend around and meet at some crazed point.
