In response to the topic, I would say that yes they are a bit more cultish than the rest, although I agree with popular opinion here that it is a matter of semantics anyway being that all religions are somewhat of a cult, but the major difference with JW being that they're a bit more extremist in their beliefs and in someways forcibly so. Not to mention the fact that it was started by a rich millionaire.
Their ideology is basically if you are not part of their religion and you do not believe what they say you're branded as an outsider and you're forbidden to associate with outsiders. Basically the message is if you do not accept their word as gospel truth you will die on judgement day when the Armageddon comes. Almost like a cleansing if you will. There is no such thing as a heaven or hell when it comes to human beings. It's only salvation and damnation. If you survive you will live in a God made paradise right here on Earth and if you die you just cease to exist period, no belief in souls or spirits but they do believe in angels and demons and satan himself except instead of reigning in Hell he walks among us right here on Earth. No belief in purgatory..etc.
I had a friend who was a JW, they're rules were extremely strict. He was not allowed to make friends or have girlfriends outside his religion. He was not allowed to fornicate or even engage in any behavior that would eventually lead to fornication. He was not allowed to celebrate holidays or even his very own birthday. He was a great guy, real funny too, had a great sense of humor but in the end under pressure from his religious brothers and his family, he ended up choosing his religion over me. I understood, to each his own I suppose. I still kinda miss em to this day. I truly hope he's happy and wish him nothing but the best. Btw, the thing that made him so funny is that among the things I mentioned you were also not allowed to curse, this guy could crack you up without saying a single curse word, that's how funny he was.
As far as the article goes, either this whole story is bogus or that woman doesn't remember her teachings well. JWs believe in Jesus Christ as the Son of God. They believe in God 'Jehova' and Jesus Christ his son. They do not believe in the so called 'Trinity' ideology of them all being the same person or of Jesus as a God himself, so this part of the article is definitely incorrect and completely untrue.
