The purpose of (most) speech is to create action. If the phrase "I'm going to kill you" is intended to alter someone's behavior. If property is involved, whether it's through force or threat of force, it's still robbery. If the threat of violence is delayed, it's still extortion. For libertarian extremists who, just treat the right to be left in peace to live your life as you see fit... as a property right.
