No, it will not stop up the TSA in any way. It won't take them any time at all to tell you that "you ain't flyin' today; so turn around and go home." You will find that the TSA won't care very much that you paid a bundle for your T'day travel tickets. (And, since you've already bought and paid for that non-refundable cheapo fare, the airline is not going to care very much that you missed the flight with your juvenile actions at the screening point.) If you do not do the body scanner, then you will submit to the pat down, or you won't be going home to Grandma's house for T'day.
Complain to your Congressman all you want. Let's hope he didn't get voted out of office in this last election. He may not care, either.
