This question (as well as a few others by the same OP) is scoped to seek answers from "non-cults." This terminology concerns me greatly, and lead to some comments, and eventually a chat discussion on the matter.
I see two problems with the term "cult" as it applies to our site, and specifically as it is being used in this question to define the scope of the answer.
"cult" is so broad a term that it includes literally every Christian denomination/group/church.
a system of religious veneration and devotion directed toward a particular figure or object.
By this definition, even "Christianity" as a whole is a cult.
"cult" is too subjective to be a meaningful scope-limiting term.
a relatively small group of people having religious beliefs or practices regarded by others as strange or sinister.
Every group of Christians is called a cult by at least one other group of Christians--to say nothing of what non-Christians say about Christian groups.
Early on we have decided that our site's accepted definition of "Christian" is simply any group that self-identifies as Christian.
It seems to me we ought to apply the same standard to a term such as "cult." If any group self-identifies as a "cult," it ought to be fine to use that term to scope questions. Otherwise, the term, in my opinion, is either all-inclusive, and thus adds nothing to the scope of a question, or the term is used to limit the definition of a "true" Christian (which violates the above mentioned definition anyway) and is entirely subjective, and therefore also doesn't add anything meaningful to the scope of a question.
We also have a question on the main site about the term cult, and the accepted answer says:
There are of course alternate definitions.
and additionally offers the following insight:
While it is possible to be used in a meaningful way, the variety of uses mean you should always check what the speakers definition is. The usage of the term will often tell you more about the beliefs of the person using it than those being described by it.
So in summary:
