Comparing a natural ability to some kind of privacy-violating skill sounds a bit a hard sell.

Kind of like selling hard won skills as some kind of gate keeping.

Improving the quality of life of people cannot be done at the expense of the basic social needs of everyone else.

I wasn't saying any of the words you seem to be putting in my mouth.

I was simply noting that there's a natural range of both abilities and expectations in this area, and it is a little entertaining that even the hint of a suggestion of an implication that maybe face recognition is perceived differently by different people provokes such a strong, fact-free response.
