Hmm. I am ambivalent on the idea of "ritual nicks."
In the United States many boys are already circumcised and adopted into Jewish families. This is still not "fine, whoop-dee-doo." Something similar to what seems to be described here as a "ritual nick" has to be preformed to enter the covenant, even though the baby's already circumcised. If the baby isn't, or the kid is older and isn't, whatever, no one's going to take him away, but he'll have trouble if he wants to become a rabbi or something.
So, the mutilation is not the point. The covenant is. What is more important to these people, the religion or the repression of sex?
