how much longer do you think it will be til the borg implodes? Predictions of the Jehovah's Witnesses are bound to fail for the simple reason that when an organization reaches several tens of thousands it virtually assures itself immortality. As I've brought out recently, on another thread, the Rutherfordian power struggle that lasted decades, and saw the creation of several sects, diminished their membership down to as little as 25%. Yet they survive.
Furthermore the reasons you have stated are not sufficient individually or collectively to bring down an organization immune to reason.
with april's rediculous generation renewal, It could get even more ridiculous and yet it will be passively accepted. You have to realize that most JWs were not even in the organization when the teaching that most of us are familiar with was taught. And if they have a problem with that then they become part of the huge turnover of disaffected JWs.
the hyped 2012, Are the Jws hyping 2012 or somebody else? If they are not hyping it then what's the point?
then the 100th aniversary of 1914 two years later,Which goes back to the "generation" issue. 1914 has been devitalized, it is no longer a pointer by means of the "generation" of the end so the JWs simply shift to the 'signs of the times to get what little adrenaline they have.
the continued increase and spread of internet use, This may slow down its growth by some and keep them from refreshing their numbers in the USA, other English speaking nations and Europe but you are assuming that most people investigate the religion that they choose. They no more do that then they investigate anything else in life.
the age of the GB,They'll find a way to get fresh blood before they collapse. A better issue is the age of the elders.
and the lackluster of the rank n file, i give it 8-10 years before the whole show collapses. They are demoralized but this is where we have to take into account the context of JWs in the world. This world is going to pieces, though not for reasons that the Gibbering Body of imbeciles, The Faithless and Indiscreet Master predicted. Apocalyptic religions like the JWs are nurtured and grow under periods of distress. All they have to do is emphasize Matthew 24 and adjust current world events with their bastardized reinterpretation and that's it.
