Of course, I am a classical liberal, and like Voltaire, I may disagree with what they say but will defend to the death their right to say it. Because that stance embraces my right to call them on their asshattery.

Off topic, really, but I've been wondering about this principle lately. If some guy is standing on a stage, urging people to lynch me, am I ethically justified in infringing his free speech by headshotting him?

If I am ethically justified in that infringement, what if he's simply urging the crowd to bind me in chains and set me on the road gang, rather than stringing me up from a tree? Do I still have a clean go-ahead on squeezing the trigger?
