There's no 'wobbly bits' or even a 'skeletal image' but just an asexual stick figure on the image.
I can't see how anyone would rather be touched by a stranger than go through this box for 2 seconds.
Pat down is not an alternative option. If a person cannot for medical reasons go through the scanner, other forms of technology will be used and this will certainly take longer than the full body scan. So if someone is concerned about being separated from their possessions, the scanner will be the quickest way to be reunited with them.
I suppose those who complain about the hazards of these scanners found out about them by searching online using their mobile phones - which emit more radiation than the scanners.
I'd love to know how walking into a box and lifting your arms for two seconds is 'degrading' or 'stressful'.
