Most of the people in our society are sheep. We may be in the most violent times in history but, [in America,] violence is still remarkable rare. This is because most citizens are kind, decent people who are not capable of hurting each other except by accident or under extreme provocation. They are sheep.
I mean nothing negative by calling them sheep. To me it is like the pretty, blue robin's egg. Inside it is soft and gooey but someday it will grow into something wonderful. But the egg cannot survive without it's hard blue shell. Police officers, soldiers and warriors are like that shell, and someday the civilization they protect will grow into something wonderful. For now, though, citizens still need warriors to protect them from predators.
