I guess I can't, or my subconscious can't, even imagine a warless world. The best it can do is substitute one kind of war for another. You said, no killing of humans by other humans. So I dreamed up the Aliens. Your own ideas are sane and rational, but this is my unconscious you're trying to use, not my rational mind. Maybe rationally I could conceive of the human species not trying to kill each other off by nations, in fact rationally it's easier to conceive of than the motives of war. But you're handling something outside reason. You're trying to reach progressive, humanitarian goals with a tool that isn't suited to the job. Who has humanitarian dreams?
