AP, I think there are only a few choices:
1) Don't fly. This is a very common response.
2) Fly, and trust you don't get asked for the pat down or the back scatter machine. Gotta have a plan 3 or 4.
3) Go htrough the machine. Asked to go through the backscatter :I don't think the machine is much harm.
4) Asked to go through the backscatter, decline, and then get the "pat dowm." Your mileage may vary. I have not encountered this yet. I will submit to the pat down and inform them that I find it very humiliating ! do) and they should find it very humiliating as well.
5) I think we should start profiling.
6) I don't think the TSA folks drive this, but they go along.
7) Everything else, just can't talk about this.
