I've been flying dozens of times over the last few years. Never groped. Never patted down in some molesting way. Never been a victim of all of these overblown statistically small events being made into huge life changing altercations. Every interaction I've had with everyone has been normal. Even the few times I've forgotten and left a full can of spray deodorant or liquid in my bag, they've pulled me to the side, opened my luggage in front of me, asked if I'd like to check my bag or toss the item and that is that. No harassment of any kind.
Acting like a dick to TSA employees just makes them treat you with even more contempt, thus the vicious cycle continues since they now have disdain for you as a customer.
Do you treat all car salesmen like crap, or people at the BMV, just because they have a general "bad" reputation?
Also do you object to a pat down when you go to a sporting event or concert? What about a courthouse?
