I am very angry about terrorism. I think terrorism is a very bad thing and we should eliminate it from the world if we can.

Being very angry about terrorism =/= thinking that a good way to solve the problem is to randomly go kill the entire population of the Middle East in the name of freedom (and oil). I hate terrorism and would prevent it if I could. In fact, I hate people killing each other so much, I think we should think rationally about the best way to eliminate it utterly (whilst causing fewer deaths than it causes) and then do that.
