Libertarianism is NOT pacifism! I am all for implementing libertarianism through force. Anybody who acts against libertarianism needs to have force used against them until they stop acting in such a way. There is nothing immoral with forcing libertarianism on the world, that is like saying it is immoral to force a person to not kill an innocent or immoral to force a thief to stop stealing. It is immoral to not use force to implement a libertarian world!
