If one lists all the possible problems in the world, circumcision would rank around 12985324th

Why would a man with a whole penis be "jealous" of one who had part of his forcibly cut off? Are you insane?

Cutting off healthy body parts will prevent cancer from growing there, but that is a serious violation to cut off part of someone else's body part to "prevent them from cancer." What a specious and vapid reason to mutilate the genitals of a child.

Cutting off healthy body parts is not "corrective" it's mutilation and wounding.
