El Greko...quite right, that was a bit of a stretch. However, anyone who thinks that a topic as huge and complicated as this will produce any meaningful answers, especially on an informal "folk music" forum, is also stretching. I am quite sure you know that our actions toward each other, on a personal basis, are well within our control. As the circle gets larger, we have less and less control. By the time we are dealing with nations of 1/2 billion people or religions of a billion people, each of us, as individuals has little or no control over what happens.
