10 Those who make use of the media of communications, especially the young, should take steps to accustom themselves to moderation and self-control in their regard. They should, moreover, endeavor to deepen their understanding of what they see, hear or read. They should discuss these matters with their teachers and experts, and learn to pass sound judgements on them. Parents should remember that they have a most serious duty to guard carefully lest shows, publications and other things of this sort, which may be morally harmful, enter their homes or affect their children under other circumstances.
