The way I see it: we were very proud of our Bill of Rights, but never came up with a corresponding Bill of Responsibilities. You wouldn't expect one, of course, but the Bill of Rights gives people a thing to hold up and declare "I got mah rights!".

Pretty much any time you see somebody clamoring about their rights, and ignoring any talk about responsibility (or talking about your responsibilities but not theirs), you can tell the conversation isn't going to go well.
