It's not the modesty aspect of the backscatter x-rays that bothers me, it's the radiation. I have been exposed to more than my share of x-rays over my life, so it worries me to possibly raise my cancer risk by being exposed to more. I'm not at all worried about someone looking at my body image in a remote location. After a screener has seen a few hundred folks' x-ray, I'm sure my body won't look particularly interesting to them.
Not sure how I feel about having a pat-down. Sounds like they vary widely in how "intrusive" they are. I feel for the man with the urine bag, and women who have had to remove breast protheses; and I completely get how those who have been sexually abused could have problems being touched in this way. I am not sure I believe stories about tampons being removed! As I understand it, the pat-downs are supposed to be outside the clothing. I am sure I wouldn't enjoy being touched that way, but it might be preferable to the radiation, as any embarrassment would only last a minute or two, vs. radiation, which is cumulative.
I'm just not quite sure what I'll do the next time I fly if I have to make this decision.
