Brian Sodergren, the man behind the National Opt-Out Day movement is currently traveling by car—effectively opting-out of Opt-Out Day. You're currently pissing off a TSA agent by demonstrating your principles. I really hate both of you.
Here's the thing: There's something exciting at the end of every flight I take—be it next month's company party, a last-minute visit to a lover, or a family gathering. Hell, I'd even find flying out to personally deliver lunch to my boss more thrilling than a prolonged wait in an airport security line.
And because of all that excitement waiting on the other end of a trip, I'm not shy or hesitant about doing what's necessary to get through a security line as quickly as possible. My luggage is perfectly packed, I don't try to bring any questionable items past the security check, and I don't mind being scanned or patted down. I understand that the people I'm interacting with are just doing their thankless jobs and try to make my own life simpler by not making theirs difficult—I'm basically a TSA agent's dream passenger.
I understand your concerns about the potential health risks associated with body scanners. I get that you're worried that your little Susie or Billy will be confused about the principles of Good-Touch-and-Bad-Touch after a TSA pat down. I can comprehend that you're shy about some TSA agent in a dark room seeing a shadowy outline of your naked body. I think it's great if you're informed about body scanners and how they work, which airports use them, the flaws of some machines, and what happens if you really don't want to go through them. I have no problems with your concerns, principles, and complaints.
