I'm against security theater and all for asserting your rights at the airport. But that doesn't change the millennia-old fact that if you want or are dependent on someone for something you should probably avoid being a dickhead about it. If you want to opt-out of the scanners, opt out. If you want to ask if this or that process is required, or why, just ask. If you don't want to speak, don't speak.
I like to think about MLK in these situations. He was fighting for an incredibly just cause, yet acted respectfully and understood the consequences. If you're acting like more of a dick than he was, your cause had better be bigger than his was.
