It doesn't make sense that his foreskin should arbitrarily be cut off just because they did it back when I was born.
Routine circumcision is a colossal mistake.
The same mistake should not be done to him simply because it was unfortunately done to me. Two wrongs don't make a right. It's got to stop somewhere. But if a difference is noticed, the absent foreskin can be so easily explained. They used to think removing the foreskin was necessary.
