This is going to get a bit confusing. We're in a category that lists sites opposed to various religions. The "Cult" subcategory lists those groups which are opposed to various religions they deem "cults". These groups are generally called "Anti-Cult", but their subcategory is named "Cult", because that's what they're opposed to.
*This* subcategory has the sites opposed to the "Anti-Cult" groups. It's kind of the "Anti-Anti-Cult" subcategory.
Most ACM groups seem to take the legitimate public fear of destructive doomsday cults, raise it to a fever pitch, and then direct it against benign new religious groups. http://www.religioustolerance.org/acm.htm
