@Catdog @Bubjazz That's a Uganda study, it's designed to sell circumcision equipment and attract otherwise healthy patients to fork over the money for a circumcision.
@Catdog @mariaRB Catdog, it's also true that removing ears improves a person's hygiene and doesn't actually harm the structure that does the hearing (which is internal). Ears often get damaged during sports and in accidents, which can lead to a lot of unnecessary pain. I don't think the case for cutting off children's ears is "open and shut", and very few studies have been done on this. Also, I'm not sure there's much of a philosophical distinction between a child and an adult... so I've consulted with your parents and we've decided to sneak into your house at night when you least expect us, and we'll hold you down and cut your ears off. But don't worry, we'll use topical anesthetic.
