"If you ask parents why kids shouldn't [violate social norm X], the less educated ones usually reply with some question-begging answer like 'it's inappropriate', while the more educated ones come up with elaborate rationalizations."

I see no loss of meaning, but that's probably because there's so little meaning in the dismissive little excerpt you've chosen to deploy here.

My kids aren't allowed to swear either, for exactly the same reason that this commenter gave. People who think words can't be dangerous, especially for a 10 year old, seem likely to me to be leading sheltered and confined lives.
