One problem with Libertarians (big L) is they think incrementalism goes in both directions. It doesn't, the pendulum is a ratchet. Another is that any political gains they do make are at the pleasure of the powers that be. They'll always be subservient to whatever system is already in charge. I'm still (small L) libertarian and agree with Kienan. I don't see any inconsistency between the minimal state society and "Communists must be physically removed." It's a hard rule. You have to win the war first before you can replace the system.

The problem with that though is the other one shared with communism: To get there you need a strongman to utilize the State to destroy the State. In practice it doesn't happen. At best we'll emerge from the rubble with a better State for a while, which most people here would be fine with.
