I have very little objection to disrespecting the disreputable aspects of "culture," mine or anyone else's. If it hurts other people then it doesn't get the protection of etiquette. The baby ear thing is something that has never made sense to me.
Girl friend and all time top contender for title of Mrs. has never gotten her ears pierced. It's rare enough for people not to do that, that I think it is neat. Seems more normal even though it's less common.
Insurance companies in the US traditionally would not insure valuable earrings unless they were for pierced ears. I don't know if that is still the rule but it was at one time.
Clip-on earrings fall off and get lost easier than earrings for pierced ears.
