Any state has to allow for the distinction between insiders and outsiders, which is why arguments that "no one is illegal" are more romance than viable policy.  But democracies and republics are built on laws that descend from principles of universal civil and political rights, and if the divide between citizen and foreigner becomes too broad, if foreign and domestic policy are not just separate but contradictory, there's no way for one not to affect the other. You cannot support freedom at home while opposing it abroad; the inconsistency itself is a recipe for disaster.  The right and the left both understand this. Liberals don't.

The sudden howls of indignation are pathetic.
