A few specifics Without wanting to fall into legalism and not intending to give the impression that I have the right or ability to dictate what is good or bad, allow me to get a little specific. On the negative side, we should steer the children away from all gratuitous violence. For example, we should not allow computer games whose sole purpose is to destroy something or to kill people into our homes. We should be aware that many toys and especially cartoons are teaching the children to think that magic is normal. They are drilling home the message that the supernatural lies in the creature.
Creatures become gods.
The distinction between Creator and creation is blurred. Often the toy or the cartoon character will have a shiny jewel on or in its chest which has magical powers. Think of care bears and trolls. George Lucas, the producer, has embraced eastern mysticism and pantheism. Movies such as Star Wars promotes these religious philosophies.
