I agree for points one and two, further points are the best way to go for a loooooooong journey in a little room. They have way more time than you have and they know it. The whole game is to make _you_ being embarrassed about the pat-down so you'll finally go through screening next time. This whole game is totally unbalanced in a way, your ressources to make them retreat are absolutely insignificant in front of the whole machine (on spot that is). The only way out of this craziness is political so don't hesitate to give a call, send a mail to people representing you.
