I've noticed a lot of misconceptions concerning libertarians and what they believe. Rather than accept what our ideological opponents say we believe, I would appreciate it if anyone on this board would ask me any question they want.
There are a lot of defintions of what libertarians are but I like L. Neil Smith's. There are others. And there are disagreements among liberarians about what does or doesn't constitute force and what does and doesn't constitute consent. But all political movements have disagreements. Liberarians are no different.
"Zero Aggression Principle":
A libertarian is a person who believes that no one has the right, under any circumstances, to initiate force against another human being for any reason whatever; nor will a libertarian advocate the initiation of force, or delegate it to anyone else.
Those who act consistently with this principle are libertarians, whether they realize it or not. Those who fail to act consistently with it are not libertarians, regardless of what they may claim.
— L. Neil Smith
