Part of the attraction of the occult and the pseudo-pagan has to do with the pretensions of being part of some older and more sophisticated tradition. Since there are no unbroken lines of tradition linking back with the ancient Moon Goddess cults, the make-believe rites and Halloween costumes satisfy the curious. And the thrill seekers.
And don't forget the desire for gnosis...one of the pitfalls humans fall into time after time after time...the desire for the secret knowledge that only the special or the elect or some inner group is privy to.
