Ah. But take a libertarian (like me 20 years ago--small and large L) and let him watch the social libertarianism of the 60's crash thru our culture, destroying everything in its path.
If he cares about how his philosophy jives with reality, he realizes that libertarian assumptions about human nature in regards to moral issues are fundamentally flawed. And it's pretty clear at this point that America's experiment over the last 40 years with social libertarianism has been a monumental failure in almost every regard.
OTOH, where libertarian beliefs align with human nature (in the economic sphere), it is a practical philosophical overlay to political decision making.
Libertarians who come to that realization become conservatives. The difference is we do not blindly apply one principle (small government) to every problem. It's a lot harder being a conservative. I no longer have a simple answer for every problem.
Yep; those perfectly good signs are trash in some dumpster by now....
