Something is happening. It is happening nationally and locally. It is an ideology that manifests itself in graveyard desecrations, animal mutilations, human sacrifices and suicide. It categorically involves drug/ alcohol abuse, pornography, sexual perversion, physical/mental abuse, heavy metal music and drinking blood. And it is highly organized. Satanic/Occult organizations (churches) have corporate charters, own buildings, maintain national/ international computer networks, publish magazines/newsletters and hire professional public relations firms to polish their public image. It is both generational and self-styled. Some groups are esoteric while others are pantheistic.
