> flying is a privilege, not a right
Is taking a train a privilege, not a right? Driving? A bus? Would you be okay with TSA-like screening procedures before any such sort of transportation? What makes flying so special? People have bombed trains, cars, busses, etc before too.
> "The terrorists have won" because you had to go through a machine? I think it's time for the OP to step back, take a hard look at their life and wonder if they have their priorities straight.
Maybe because our government has taught the citizenry that it's okay to be pre-emptively searched on planes, or stopped and frisked (http://en.wikipedia.org/wiki/New_York_City_stop-and-frisk_pr...), or other such things. Meanwhile, the rent-a-cops operating these machines are basically given free reign to do whatever power tripping they want, because one wrong move can have you finding yourself detained for a while.
