ummmm - //It doesn't hurt. //
That doesn't make it right though, does it?
Apart from which, I seriously doubt your point - do you really believe that no baby, on having her ears pierced, does not make enough noise to be heard three streets away? I doubt it.
By the same token, putting a bone through her nose may not 'hurt' either, but that doesn't make it justifiable behaviour.
Punching holes in babies' ears in order for the parents to think they look 'cute' is not acceptable behaviour in my opinion.
