Anyone who would sign up for this filthy government program should have their citizenship stripped.

The only thing I can think of that would be more disgusting is a mandatory registration. If enough un-American blowhards sign up for the voluntary version, the TSA and their hangers-on (you know, stupid people who never fly, which is, sadly, a large number) will say "Well, this is such a popular program, let's make all passengers go through a background check. People who refuse will be banned from flying."

Cell phone number? Home e-mail address? What the F are you people doing giving away this information, and to the government of all places?
