I am sorry if an "indoctrinated" doctor (think about that one for a second) cut off the tip of your penis, it doesn't mean you have to justify it by doing it to your own child. Little boys deserve to have 100% of their penis intact.

I think that developed as a medical procedure for a matter or health in some specific zones of the planet, specifically hot and dry places. I may be wrong, but the medical part comes after the cultural and traditional element in such situations.
I doubt that. That might be a story that is told.. It's not that hard having a "foreskin" As a dirty kid in the desert, I learned to clean when it got itchy. 🤷
