The question should never be "why should we protect $SUBJECT" (where $SUBJECT is anything, not just children), as that question implies an allow-by-default policy. Usually, this is done to shift the burden of explanation away from those actually doing the actions in question. Instead, the question should always be "why should we allow $ACTION". Show why $ACTION isn't going to cause problems instead. The "default permit" approach has never been sane security policy, as it presumes you are able to enumerate all possible current and future threats.
