Oh, there are societies eh? Which societies. Those that no longer exist you can exclude because we dont need to emulate failed societies...
Our society has never "failed", and yet it exists in a form entirely unlibertarian compared to its past. Perhaps you can see the error in your thinking.
Sounds like waffling... Especially with the relative thrown in as a modifier...
It depends on context. I rarely waffle on my libertarian convictions, although I do change my mind when presented with sufficient reason.
However, I may describe Ron Paul as "libertarian", but I do so only in comparison to the rest of the party of which he is a member. He is by no means "libertarian" in the same manner as myself, or even what I would argue to be to the same extent as myself. That does not mean the "libertarian" identifier does not carry some accurate meaning when applied to the man.
What country, that isn't authoritarian, has been a success?
I'm sorry, but you'll have to define "authoritarian". It is itself a relative notion.
If you mean to suggest, "a place where authority exists", the question becomes meaninglessly exclusive. If you mean:
authoritarian |əˌTHôriˈte(ə)rēən, ôˌTHär-|
adjective
favoring or enforcing strict obedience to authority, esp. that of the government, at the expense of personal freedom
The US, at its inception, was not authoritarian. It was a success by any measure, aside from being an eventual victim of its own success. It is now authoritarian, but it still exists, and is arguably worse for the change.
The Czech Republican is not authoritarian. They have a very liberal culture, in fact. I've long considered moving there. The success of this is apparent; it has lifted the country out of the shambles of totalitarianism, and Prague is once again the jewel of central Europe. The country is easily the most liberal of post-communist countries, and simultaneously the most successful.
How many examples do you require?
