Perhaps I am missing a key element here, but I am not sure what growth or stagnation or even diminishing numbers has to do with how we feel about the religion we have left.
Often the craziest of cults, even after undeniable exposure as fraudulent, continue in some form. There are survivors of the Branch Davidian compound who still believe in what David Koresh preached. The Fundamental LDS Church continues even though its leader is in jail, exposed as a pedophile. Several tiny groups are still preaching Armstrong's odd and failed take on the Bible, even though the Worldwide Church of God denounced their leader and his teachings as a cult when he died before Jesus returned as promised. E-Bible Fellowship still functions with a small group of followers even after setting several well-publicized failed dates for the end of the world. And the Speedo-wearing guru of the cult Buddafield continues to gather followers though he has been exposed as a fraud in the CNN film "Holy Hell."
In reality, these groups and leaders, though some still have their adherrents, are over. They have had their day. They have been exposed as the liars and wellsprings of falsehood they are. Nobody in the world really gives a moment's thought to those adherents that refuse to leave now or even, God forbid, join these cults from this point on. It is clear to everyone that if you do, you're an idiot.
Don't waste your time worrying about people who freely choose to waste their time. At this point it is totally clear that the Jehovah's Witnesses are a cult. It may be a surprise to us ex-members now that we have come to accept it, but the world in general isn't going to suddenly shine the spotlight on the Watchtower and expose it as a cult, causing the movement to come tumbling down. Why not? Because the world always knew it was a cult.
They are not going to be more interested in the pedophile and child abuse news involving the Jehovah's Witnesses coming from the ARC as they were with the Catholic Church. Why not? Because the world generally sees the Church as an authentic religion, a place where such things should not be happening. But the world of the Watchtower? Like the cult groups listed above, the world gave up on the Witnesses long ago. As I recently heard one person say who I mentioned it to: "It's not surprising news. It's a cult. You kind of expect that kind of thing to be going on anyway. The only people surprised are those in the cult."
When the world didn't end with 1914 and then later the Patriarchal "worthies" weren't resurrected in 1925 to go live at Beth Sarim, the world closed its doors of interest on the JWs, heck, probably even before then.
It was surely over well by the 1975 fiasco, and the Witnesses were definitely a laughingstock then. If you had the unfortunate experience of becoming a Jehovah's Witness after 1975 like I did as a teenager who knew no better, the world in general kind of instantly gave up on you at that point. In their eyes we were like those still following David Koresh after his compound in Waco had burned to the ground. People just consider others who do such things as stupid idiots. And guess what, we were.
And it is now definitely over for that religion. It is over 100 years after 1914, they have had to dismiss almost half of their doctrine as "the light getting brighter" and spend their days rationalizing over a graph of overlapping generations to justify to themselves why they are still hanging on.
It is over. It was over a long time ago. You are looking now at a ship of fools. It never went anywhere and will never do so. The world in general has given up even laughing at them. Their leaders are guilty of abusing the children of members or are turning a blind eye to such horrors in the ranks they govern? Well what did you expect, says the world. It's a cult. Cults do things like that to children. It is sad, should be stopped, but it's also expected. It's a cult. People been saying this for over 100 years. Where have you been?
Why are you concerned over growth of anything happening in his cult? I know it sounds harsh, and every life is precious. But the proof is already there that it is a failed cult. They are not going to listen en masse either inside of outside. At this point all you have is a group of ignorant folks and the unfortunate children of theirs who get born into the group. I am not saying give up on trying to expose them, but concerned about growth? Even fish out of water sputter around on the ground for some time before totally expiring.
