Once the foundational beliefs which created the Declaration of Independence and the Constitution are shown to be false, ...
The notion that citizens should be free to conduct their own affairs without government meddling unless they infringe on the rights of another is not a false foundation...and hasn't a damn thing to do with Christianity.
How shall we proceed to reform society? Easy. It starts and ends with freedom. Try it sometime!
Why? Why is that good? Where does that silly notion come from?
Silly? Really? If you really find the notion of freedom to be silly, I don't think you can be helped.
Why is it good? Because we have thousands of years of examples demonstrating just how bad totalitarianism can be. Freedom, as envisioned in this country's founding, has proven to be the only cure against the horrors brought on by central planners. That's why.
Central planners weren't around back in 1776.
Holly crap! Did you really just write that?! Get thee to a library and read up on the past several thousand years of history. We called them Kings, Queens, Pharaohs, Dictators...all kinds of names for those that were central planners. As always, they were just SURE they knew what was best for everyone else. The freedom experiment that was the United States proved that free people making voluntary decisions is the antidote to the central planners, whatever you call them.
"As for totalitarianism, how do you propose we deal with the liberals? An equality based system which grants one man, one vote, can result in totalitarian liberals coming together and voting in their totalitarian hell. How's that freedom working for you?"
Excellent point. But not an example of freeedom. We are NOT a Democracy. We are a Constitutional Republic. We deal with the liberals by returning the notion of limited government per the Constitution, which disallows central planning beyond a few enumerated powers...which no vote short of a Constitutional amendment can overturn. At least that the way it's supposed to work.
"I'm going to guess that you're a libertarian." Yes, a Classical Liberal.
"If so, then your libertarian vision is anchored on the social values created in the Christian West." Nope, the vision is anchored in freedom. Nothing more.
"How do you imagine libertarianism is going to play out, that respect for freedom, if we drop it into Papua New Guinea or into the Democratic Republic of the Congo?" Don't know, don't care. If the people of those countries are ready to embrace freedom, limited government and personal responsibility, I suspect they'll thrive just like we did.
