No, I'm not saying that they're all always correct. I disagree with Friedman on plenty. What I'm saying is that they're generally correct enough.
I was the same way until 9-11 when isolationist libertarians (in today's world) and pacifist libertarians reared their irrational heads. Neither one is defensible, much less practical. Libertarianism is a hard enough sell in today's western world of nanny states, but denying a right to self-defense (which is what they come down to) turned off many card carrying big "L" libertarians such as myself. The sound absolutely just like libs.
I don't know enough to say whether I'd consider you a libertarian or not, but I'm willing to take your word for it despite the fact that what I do know about you says that we obviously have some different ideas.
As I said, I can and have gotten along. But pacifism, which you apparently embrace (anti-war) and isolationism are deal breakers--and you don't appear to be inclined to defend it. It's strange but some libs and libertarians can adopt the anti-war label but don't want to be called pacifists. There's no difference.
Judging people on what you consider to be the "Truth" is a pointless exercise. If everybody tried doing that then nobody could ever work together. Everybody would think they're a "real" conservative and everybody else is a fake, and the same with liberals and libertarians. It's also arrogant to assume you know the "Truth."
