We really shouldn't tolerate people like that though, should we? If you don't respect TSA agents, it's your duty to remind them of that. Our ability to change the TSA through the democratic process has been on the wane for years now, but we can still force change by making it hard for the TSA to hire. If they have to double their salaries because being a TSA agent makes you a figure of mockery, they might fondle people a bit less.
As for how they take it out on the people behind me, that's their decision. They're adults, not dogs, their behavior is their responsibility, not mine.
