I'm not afraid of an ID card, but a national ID card is a different matter. I worry that we are getting to be too willing to give up our civil liberties in order to gain an illusion of safety--that somehow this ID card will divide us by implying who is from who isn't safe. Witnessing Tim McVeigh, and all the other senseless crimes committed by our own countrymen, I don't see how the ID cards will work to make us safer. You don't have to be a foreigner to be dangerous, and not all foreigners are to be distrusted.
The mark of the beast aside, how divisive these cards will be! Will we personally distrust Christian foreingers who don't have the right card? Will we trust everyone who has a card? If the problems seem to be with millitant Muslims, will your religious affliation have to be put on the cards? What if your religion is unpopular? Will you be denied a card? What about political leanings? Will ultra-right-wingers like McVeigh be denied cards because of party affliations? What about libertarians, communists and KKK's? How much information will have to be input before it is decided whether or not you are dangerous and whould be denied a card?
If it would really work to make us safe, without causing even further fractioning of our society, I might support it. But someone will have to explain to me why it is necessary or even useful.
