Nobody is being passionate, that is the very point. It is being dispassionate that is being advocated. Emotion and the Law must always remain separated otherwise you have no Law.
Our problem arises because we have produced a generation of people who believe that there is no such thing as evil because it means they failed. They have their own guilt consciences to hide behind whether it be as a result of the War, or a misguided belief that if they are not a threat to anyone, then they are perfectly safe. This generation, of which I am one, has passed on its guilts to the next generation, who in the absense of any form of control, are doing what any species does when out of control. That generation will in turn pass on to the next and then pretty soon, we have no civilisation at all.
I believe that in order to protect the majority of people who do believe in civilisation, then we must protect them from those that do not. Of course life is always a pendulum and we must try to stop it swinging too far in one direction or we have scenarios where extremism can take over. The history of the last Century cleary shows that and it is natural for people to try to avoid repetition. But as in the last Century sooner or later you have to make a stand, or be destroyed.
