When a man walks into a crowded theatre and says FIRE and the reaction is panic and people die and yet there is no fire.. is he not guilty of manslaughter at least? Now he could have gone into an empty theatre and shouted FIRE .. that is his right under freedom of speech and the reaction does not cause death and panic.. but he choose.. yes choose to walk into a crowded theatre and shout FIRE which in turn caused panic and deaths. He knew what was doing and he is responsible for his actions.
One of the cornerstone of our societies today, and especially of the right wing political theory.. is personal responsibility. You are responsible for your life, you are responsible for your actions.. and you are responsible for your words. If ANY of those responsibilities cause harm to others.. then YOU are responsible either in part or in whole for those injuries.
