I always “opt out” so as to get the free TSA “massage”. Also, it seems to irritate the TSA types that someone would have the nerve to inconvenience them. I’m not sure my smile and smirk help at certain junctions of the experience.
Re: opting out.
Good idea. Besides a bunch of the other problems with the scanners, alluded to in this thread:

there's the fact that maintenance / calibration procedures are so poor that
one of the machines caught on fire at LaGuardia this weekend.
I mean, really ... even if the machines were designed to be safe, how confident could anyone be that they are operated within safe parameters? This question is valid for the X ray and the microwave machines, of course.
