Thank you for doing your part. Every time you opt out, people may notice. The more you opt out, the more you may inspire others to do so. The parent's argument is a self fulfilling prophecy.
It's also a good way to put totalitarianism on display out in the open, rather than letting it lurk quietly. It's amazing how nobody wants to make eye contact with you as you're being groped and fondled.
No, it doesn't. It annoys all the other travelers whom you are inconveniencing by slowing down the screening process. The TSA people who screen you are just going to follow their standard procedures in response to whatever you do; it's all the same to them.

The individual person who has to screen you might be annoyed at that moment, yes, since the procedure they now have to execute is more complicated. That doesn't mean "TSA" is annoyed. To that individual person, you are just one of many transitory annoyances that are part of a normal day at work.
