Principles or pragmatism?  A choice that libertarians face numerous times every single day in life.  I am certain that every libertarian chooses pragmatism – not every time they face a choice, but enough times to matter.  We each individually choose when and for what reason we are willing to compromise.  We each decide every day what lines we are willing to cross.

Those who consider themselves the most principled are never shy about abusing those whom they self-righteously judge to be less so – all the while ignoring the planks in their own eyes.

Principle

Myths, Misunderstandings and Outright lies about owning Gold. Are you at risk? 

Define a violation of the non-aggression principle.  Murder and robbery are easy.  We disagree on many other issues – are they violations or not?

Define self-defense.  Define aggression.  Define punishment.  All subjective terms.  (This is where that pesky thing is known as "culture" comes in – a real difficult subject for some self-labeled purists to grasp).  Given this…what is principled?  One libertarian's "principled" might be another libertarian's "pragmatic," and neither be "wrong."
