But is the solution to this 'occult threat' vilification? I don't think so. I also don't think the solution is to teach the children to regard it as fantastic or utterly harmless dallying.

If something is to be done about it, it must be Education. Teach your children what is, and is not, possible, why some people think they possess powers beyond those of normal humans and what kind of trouble they can get in.

Teach them what role 'magic' and superstition play in human culture, and how different these roles are from those portrayed in fantasy settings. Tech them the nature of fiction and escapism.

Of course, if you've already taught you kids that there is a Santa Claus, you might have some credibility issues on the subject of magic, either way you take it.
