Anecdotally, flying yesterday when I went through security I declined the scanner and was simply waved through a regular metal detector. I also did not remove my belt or shoes. Kind of a pre 9/11 screen. 2 months ago at the same airport I got the full-on scrotum poke.
I was a bit jetlagged so I didn't raise my concern quick enough, which I fully admit is my fault.
They basically herded my fiancee and I through the machine without telling us what it was or that we had any option for a pat down. That's what bothers me the most I think. They seem to be ok with subjecting people to this without telling them or presenting them with the choice.
After careful consideration being molested by the state would have been my preferred method of security authentication, given the opportunity.
