William Lane Craig on "Is Mormonism a Cult"?

Link here.

Craig makes a sound argument and has many sensible point.  I would pick a nit with him about equating "cult" with "non-orthodox Christian."  I would understand that when the word "cult" is not used in its strictly accurate sense of a group of people organized around a particular devotion, it implies people who are under the extreme, excessive and/or unhealthy control of some person or institution. There can be non-orthodox Christian "cults" in that latter sense, such as the "Heaven's Gate" cult, which was, after all, a "UFO cult."  On the other hand, it is not at all clear that Mitt Romney or any given Mormon is a "cultist" in the same sense that a member of "Heaven's Gate" was a cultist.
