I happen to know a young man who was circumcised at 16. He bowed to social pressure to look like other boys. I still don't know why his parents allowed the procedure.
I talked to him about it and the pain was very real.
So tell me just because one cannot remember pain does that mean the pain did not exist? If we agree to use that as a standard, then any type of physical pain inflicted on infants is acceptable because what the hell, they won't remember it right?
You suggest this as if a vast number of 16 year-olds are getting circumcisions. In this particular case, it's obviously the parent's fault for not doing it sooner, if they were going to do it at all. Did they put the boy to sleep? If I was a 16 year-old choosing to do this, then I would do it under the conditions of being put to sleep while it was done.
As far as causing pain to a child, you cause pain when you change a diaper when the child has a diaper rash. You cause pain when you give a child a shot, or when they prick their heal in the hospital to take blood. Pain is all in perspective...which is why some people have higher pain tolerances than others. Getting circumcized stems from religion.
There no negative physical or emotional effects from 99.9% of circumcized kids.
