RE: "Oh, right — you see that macho culture all over such places as Cambridge and Berkeley.....,etc"
Actually one CAN find that macho culture in much of flyover country. Senator & author Jim Webb explains in his book how it's because of that culture that our nation has survived as long as it has. Someone once said, "No civilization can achieve greatness if it does not allow room for obstreperous males." We have just about reached that point.
