Bravo Bryan. I agree entirely.

No, Bill, it's not the same thing as a draft card or a drivers license. I have carried the one too, and didn't mind and still carry the driver's license. They are/were issued for specific purposes, although the driver's license has since become the closest thing we have to an all-purpose ID. But no one is compelled to produce it for ID purposes, although you might have difficulty getting a check cashed, or buying cigarettes (if you are borderline age) if you elect to refuse to use your license as an ID. Every modern tyranny, like Nazi Germany and Stalinist Russia, to name the two most obvious examples, has been quick to force its citizens to carry some sort of ID document by which the government enforcers can control them. Even some old tyrannies did the same (remember Jean Valjean and his yellow passport?).
