By contemporary standards I am hostile to almost all forms of organized religion and thought and what Thomas Jefferson called "every form of tyranny over the mind of man." I believe that many people find use and comfort in such things, though, and respect the institutions for the value they bring people.
Most of the concerns I see about MKP in this thread could be applied to almost any mainstream religious or fraternal organization, as well as to many hobby clubs. I don't think that MKP is any more cultish or inappropriate than the average church Sunday school, and believe that videogames and online forums such as this have probably damaged more marriages than MKP will ever touch.
If one is psychogically fragile or has narrow religious views, anything outside of those views will seem cultish, Satanic or weird. Such is the brittle nature of some minds, and God bless them. If they need such structure, terrific, but comparing MKP to LGAT's such as Est or Landmark seems to me silly. And certainly they do not rise to the level of Scientology, the Unification Church or Hare Krishna. Mormonism is waaaay weirder than anything I've heard of in MKP, and I think that is important to say.
A more useful and less alarming selection of culty checklists may be found at [
en.wikipedia.org] and by almost all such criteria, MKP's "culty" aspects are small beer, no more sinister to me than most youth summer camps.
A lot of good and bad things will happen after other things, but "post hoc ergo propter hoc" is bad logic.
