How easily are many falling into the trap of "common good" - please think about it, almost a century ago there was a time in one country in Europe where one nation was called to spread plague, only a few years later this nation was put to gas chambers. We are going to face the same situation very soon.
If you won't have respect to the other side you will see terror, and you will always find nice and round argument to justify that terror. Seeing how much of hatred is spread in this "technical" forum I must say, the time of terror is very near.
