Oh please. Probably 99% of circumcisions are done on normal penises and normal foreskins. In the case of that 1%, there are isolated cases where a foreskin is deformed or a cause of disease. The actual number of "medically necessary" circumcisions are minimal. It is, in most every circumstance, an elective procedure, and, as this thread has demonstrated, there are those adults who have elected to have it done and are glad to have been circumcised, and then there are those (like my friend) who hate that it was done to them.
How many children with normal, perfectly straight teeth are forced to have braces? If this was the case, I'm sure the orthodontist would probably want to call a social worker and have the parents' sanity examined.
As I've stated before, if adults wish to mutilate themselves, then, by all means, go for it. There's been cases of men having elective castration too. Whatever floats your boat. But when it comes to those under the age of consent, those kinds of medically unnecessary procedures should be banned in every case, with no allowance for "tradition."
