I'm not entirely clear on what you're getting at, but certainly the very nature of a "custom" is that it is something that tends to be passed down from one generation to the next. As for the fathers, I don't see how it modifies anything I said since the fathers were almost 100% circumcised as infants themselves.
Circumcision was routine in US hospitals until lately. I had my son circumcized, then all the brouhaha started over it in the last 10 years or so, thanks Dr. Dean, and I started feeling guilty, so I asked him if it bothered him. He said it didn't bother him.
Now one grandson wasn't circumcized, and got a very nasty infection when prepubescent. He ended up in the emergency room and they asked my daughter if she had taught him to clean himself properly. How are you supposed to know to teach your male child that if somebody doesn't tell you?
It gets more personal, but I would prefer a circumcized man for a marriage partner, because I think there is a lesser chance of passing on that virus that causes cervical cancer.
