Libertarians do not understand that not only is our enemy no longer at the gates; he is rampaging inside the city walls. And he does not recognize the concept of neutrals or bystanders. We no longer have the luxury of debating whether taxation is theft or whether stop signs violate the non-aggression principle. Libertarian debates were always luxury goods that were possible only in a peaceful, cohesive society where both sides accepted the same principles of honest discourse. But now, when the enemy does not want to debate you, but instead wants to silence you so that he may demographically destroy you, there is no framework for a reasoned discussion of policy.
