Well, obviously don't get me started on psychological classification and diagnostic criteria. Those only work because a trained practicing psychologist can tell the difference between the ordinary form and the pathological form of those criteria (subjectively and through experience); in the hands of a layman they might as well be a recipe for hypochondria. The real question someone is asking when they ask "am I in a cult" is not about whether you can mark your religion as "cult" on your taxes. The question is "am I in danger of harm", and it is better to ask yourself that question directly -- is there sexual or physical abuse among the members; is there a financial obligation; does the group engage in abusive punishments or penalties. If it does those things who cares if it's a cult or not; get the hell out! For the soccer team analogy a simple colloquial reading is fine -- "delegitimizes former members" : "quitters" -- "paranoid about the outside world" : "refs are crooked" -- "shame cycles" : well, that one is pretty bad, but it is not unusual for people to get significant personal gratification and the respect of your teammates for excellent performance, and to feel shame for failures. Sure, subjectivity is part of it too. But if you're looking for diagnostic criteria in that list, you have to implicitly add "in a cult-like manner" to all of the criteria, and rely on the common subjective understanding of what a "cult" is to determine if they apply.
