Well, parents have the right to choose if thier children get circumsized or not.
It comes down to religion, really. its the "hidden mark of god" to be circumsized.. read genisis.
and honestly, would you rather be circumsized when you're 2 days old, and never have the chance of remembering the pain..or when you're 16, you're in the middle-end of puberty...and you're fully cabapble of remembering it?
