Terrorism, like urban crime, is one of those things that you're not supposed to think about too much. It's fine to talk about your emotions after a bombing or a mugging. You can even share stories and eventually learn to laugh about it. What you cannot do is talk about where it comes from except in the vaguest terms of social conditions. Like pollution from industry or corruption from government, it's one of those toxic spinoffs of our modern society. It's just there and we don't much talk about it.
