Thank you, @steppingout23. I really appreciate your kind words. And you're right about perception and beliefs. Preparing this post has got me researching why and how we recognise faces. I knew a little bit already, but a little knowledge is dangerous so I'll finish my research properly before posting.

Regarding this post: I have to admit I took extra care with it since Zapiro and his team will be looking at it, and I want to honour his work....
