When I was pregnant with my 3 1/2 year old dd, we didn't know what we were having and a friend asked my hubby at work about circ'ing and he said he hadn't thought of it at all. The friend gave him 3 articles and he read them, was convinced not to on the spot and he came home and had to convince me! :LOL I finally agreed, and we had a girl, so no issue anyway!
My girlfriend was pregnant at the same time as me and they didn't know what they were having either, so I gave her the same articles and she decided not to and she had a boy, and sure enough, he's intact!
So yes, I have convinced one other person.
Hopefully I'll convince more!
