What exactly is a "libertarian"? A libertarian is a person who practices "libertarianism"; who believes in and lives by the Zero Aggression Principle (sometimes known as the Non-Aggression Principle). The Zero Aggression Principle (ZAP) states:
"No human being has the right -- under any circumstances -- to initiate force against another human being, nor to threaten or delegate its initiation."
Committing theft or fraud also falls under the ZAP as these are forms of force; they take what you have worked for with your own time and labor away from you against your will or under false pretext. Can you see how "taxation" fits in here as well?
Many, if not most, of the criticisms of libertarians I have read revolve around how the ZAP is interpreted. Some critics argue that libertarians are pacifists. Others argue that one or more core concepts of "The State" are good or "necessary evils". Still others argue that libertarians will strike out and kill anyone who angers us using the excuse that the other person initiated force. On the other hand, anyone with a functional intellect can see and understand when force has been initiated. Carrying a gun in your holster is not initiating force, even if a hoplophobe sees it and has a panic attack. Pointing that gun at a person who is making an obscene gesture at you in traffic is initiating force. Taking a person's property from them while implying that there will be consequences if the person does not comply is initiating force. Asking for a donation is not. The critics just don't get it and are not thinking. They ignore the word "initiate" in almost all cases. Probably intentionally, since they have no other argument.
