To OP,
Since you have started this thread I would suggest you define the terms "cult" and "religion" so that it is clear to everyone and yourself what you mean. The definition in a dictionary is not always the same as the connotation that the word carries to certain individuals.
For a long time the Jehovah's Witnesses didn't even refer to themselves as a religion. They self-identified as something else. What most people seem to agree on are the characteristics of the organization and how many view it them as dangerous. If you call it a cult or call it a tulc or luct or anything else...that is just a series of letters. When you get to describing what they are, then each person can decide what word or word encompass it.
