What if the behavior of the TSA worker is reprehensible? The fact that they are working hard to make a paycheck wouldn't excuse their actions. And yes, I would make anybody who engaged in activity that I thought was morally unacceptable clear that I thought they should be ashamed of their current occupation.

Ironically, I have zero problem with strict security checks at the airport, so I'm completely polite to the TSA. But I understand, intellectually, how others could be offended at their activity.
