It's a low income group composed disproportionately of people of color whose jobs make them highly visible in a service role.
In my experience, that alone explains the dislike of them as a class, although I can't see why.
Personally I've never had any negative experience with a TSA officer nor seen anyone else have one. However, given the meniality of the position, the pitiful salary they earn and the high turnover I'd give them more leeway than I would most people in terms of performance.
I'm probably biased. Flying with certain diabilities is a bitch post 9/11, trust me, and my tolerance for idiots who don't know how to deal with that is very low. So I guess my whole position is biased come to think of it.
