Though it is true that terrorism kills so few in comparison to coconuts falling on peoples heads and unfilled tires and the like, the actual effect that terrorism has on social cohesion is enormous, and a rational man should fear it for that reason. By this I don't mean the primal fear of being blown up in some bombing, but rather a fear of the effect that such a bombing has on the populace. Our societies were not constructed in the presence of such violence, and there is nothing normal about someone blowing themselves up. I'm not accusing you of attempting to normalize it, all I'm saying is that there are rational reasons to be fearful of terrorism. If terrorism is just going to be part of our society for now on, than that's one hell of a society.
