Amen, amen, I say unto you, History has entered a new era, unknown to human groups of yore. Well, not so fast. Humans killing humans is not a new thing. Drone attacks causing collateral damage of innocents is not a new thing. Considering a cavalry trooper with rifle, pistol and saber as a kind of drone, we got a lot of practice at that, gaining rule over North America -- those poor "Indians," so called. What Pat is really saying, underneath it all, is humans are not what they think they are. Basically, predators and killers and eaters of other life, just like everything else that grows. I don't care what it says in those books. If one gets used to it, one can survive pretty well.
