That is not a very good analogy to 'incitement' in the parent comment. A better example would be explaining to the police that you loudly and publically encouraged your buddies to start a brawl in the pub but then left the scene before the fists started to fly. I'm not sure where free speech legally becomes incitement though but I'm pretty sure it involves encouraging other people to do something rather then failing to convince yourself.
