Well, your comments didn't evoke any anger in me. I'm a native LA county person, having been born in Whittier in 1960. Being a world traveler, I have to say that a lot of your observations of LA are very typical of other large cities all over the world. You'll see the same "tough nuts" in Chicago, New York, London, Paris, Madrid, Sofia, Moscow, Munich, to name a few, and to varying degrees, more or less city/country depending.
That is how it is. I don't see it in terms of good or bad, happy or sad. It just is. Big city dynamics. I worked in Des Moines back in 1993, consulting at the Maytag plant in a berg called Newton, so I know what you mean when you describe the nice and genuine folk there.
