You are not being one. I don't have any pat answers, but I think that actions that smack of imposing a police state are wrong: I don't want our children to grow up in a country that once was free, but became a police state.
If it means that they will be somewhat more vulnerable to terrorists who exploit the openness of a free society, then that seems better to me than the alternative --- at least they can defend themselves better against a few terrorists than against a repressive government.
I would rather trust my fellow citizens in a free country and be wrong about some minute percentage than put my trust in an all-encompassing, repressive government.
Well I'm willing to give up in the war on drugs, which happens to be financing the Islamists. What I don't think we can do is ignore the fact that they want to destroy us. They seem perilously close to destroying Europe. With both Sunni and Shia chanting "Death to America," I don't see how we can avoid them.
