(revised February 10, 2011)
Here in New York City, there is a Cult Hotline and Clinic run by the JBFCS (the Jewish Board of Family and Children’s Services). They provide various helpful services to ex-members of “cults” and to estranged families and friends of “cult” members. They are, as far as I can tell, the only place in New York City that offers such services.
Truly harmful religious groups certainly do exist, and it’s good that there are at least a few places, like the JBFCS Cult Clinic, where people who have been hurt by such groups can get help. But the website of the JBFCS Cult Clinic associates Satanism in general with “cults,” even though the vast majority of Satanist groups (or, at least, most of the ones I’ve run into) do not fit the JBFCS Cult Clinic’s definition of a “cult.”
