Go ahead and yell
I know this will run against the grain of this thread and this forum, but if TSA wants to assign someone to view my 62-year-old penis, I really don't care. Why are some folks so concerned if some anonymous stranger sees their body? Have they never been to a hospital? Never been to a high school or YMCA locker room?
I would rather quickly walk through a machine than submit to the pat-down. I just don't think the "aversion to nudity" phobia evidenced in this Forum is as widespread as one might think if one lives here only.
I do not deny that the involuntary aspects of the machines are objectionable, but why do so many seem to object?
