Just pay for precheck.

It's $85 for 5 years, and realistically, yes, most of that money just goes to line the pockets of the politically connected. On the other hand, you can pretty consistently go from curb to club in 5 minutes, and you bypass the nude-o-scope.

I'm all for standing up for principle, but this one is already lost. TSA doesn't care if 10 ppm of the traveling population opt out. Google "managed inclusion" if you want to understand why organizing an opt-out protest on Thanksgiving (or generally encourage people to opt out) won't change anything.

Opt-out of what?

Presumably the millimeter wave body scanners, which are both invasive and relatively unstudied in its health effects.

Apparently millimeter wave radiation can be ionizing under the right circumstances. That's sort of terrifying.

The paper you referred to doesn't make any claims with regards to ionization - the effects considered are mainly having to do with the molecular dynamics behaviors of DNA.
