All dictionary and scholarly and "Theocratic" definitions aside, the common use of the term cult really refers to whether a religion (a) has unreasonable and non-sensical requirements and (b) whether the doctrine is generally accepted or not, in my opinion.
I would most certainly say that most people consider Jehovah's Witnesses a cult due to their position on holidays, neutrality, medical treatment with blood products, and shunning/disfellowshipping.
Not sure why it is a debate. If Jehovah's Witnesses are convinced they are right, why bother debating whether this is a cult or not. I would argue that under the classical definitions that the 10,000% greater emphasis and visibility of the governing body (deliberately not capitalized) makes the organization more focused on individuals than ever before.
