I'm on the fence here, but I have to tenatively side with the OP. The horror stories notwithstanding, the TSA has always been courteous and professional with me. I've been through the (old)pat downs, wandings, toothpaste confiscations, and have had them unpack my carry-on in public before, but nothing bad enough to make me consider another mode of transportation. And if anything, I think the process is actually faster than pre-TSA. Atlanta security used to be an hour minimum, and now I routinely get through in 15 minutes or less. In other cities, I ace right through almost every single time.
However, I haven't had the privilege of taking part in the new "enhanced" screening, so I'll hold out judgment until I get a full release pat down.
I can empathize with the arguments many of you are making about the searches being unnecessary, and how the enhanced pat down can be a downright humiliating, completely unacceptable social experience - but I don't anticipate it being a problem for me, especially if given the backscatter x-ray option.
