I have less tolerance for TV than they do, but I would, like Nodelman, argue for the teaching of fairytales, even though I am often offended by their values. They see violence as a destructive expression of drives and feelings universal in the unconscious mind. They speak of the inevitable frustration of the individual, of the inevitability of conflict between individuals, of the child's difficulty repressing a hostile verbal or physical response to frustration and conflict, and of her or his need to release this hostility. To act on these desires, children must be taught, is wrong. But to think, feel, or fantasize about them is not.
Feelings are never bad, wrong, or unacceptable, but some behavior is.
They show, furthermore, that evil destroys or consumes itself. There is poetic justice. In some tales, however, the heros do violently oppose their oppressors, as Jack opposes the giant. So the issue of violence in children's literature and television is complex. It may provide a way for us to educate children about violence.
