What Sandman said. And infantile amnesia is no rationalization for someone hurting and mutilating a baby. The baby still experiences it.
The only reason people have their baby boys mutilated is because they're are sheep follow what's "normal" in western society.
Luckily, less and less people are practicing this bizarre ritual.
If having foreskin was so bad don't you think evolution would have taken care of it by now?
