circumcision

"But critics say a double standard prevails: though female genital cutting is also rooted in cultural traditions, it is prohibited by law in America and considered a human rights violation. These critics object to circumcising boys for the same reasons many find female circumcision loathsome: they believe parents have no right to permanently alter the genitalia of a baby who cannot consent, boy or girl, and that far from being a useless flap of skin, the foreskin, which is densely filled with nerve endings, serves a function, protecting and lubricating the head of the penis and maintaining its sensitivity, much like an eyelid does."
