What changes exactly?
What about the fundamental doctrine of everyone dying just so you can have a log cabin by the woods.....Why not avoid the subjection to 12 window cleaner men you will never be allowed to meet in Brooklyn, do what the owners of log cabins by the woods do....work hard for it!
What about the fact that a paradise earth isn't in the bible....not ONE verse...along with 1914, 607 BCE or protecting child rapists? Who amongst you would not save a lamb in a well on the sabbath says the bible..... but need blood? abused? ....tough luck says the GB, their way or the highway! TWO witnesses only will suffice and blood was not to be eaten! .... they are unloving, unscriptural, uneducated, unrepresentative and evidently wrong as you yourself state in the implication that they may one day improve!

What exactly about this religion gives you an indication it is in any way correct about anything? Name one thing they have gotten right in comparison to the century of errors and false predictions that JW's are famous for. Including owning a military Navy company (Rand Cam), being a part of this world whilst demonising it (UN NGO) or the pathetic childish behaviour of its leaders (Crisis of Conscience &The Brooklyn Eagle).
Leaving friends and family behind is damn hard! The hardest thing you will be asked to do in life and only by dictatorial/fascist regimes or cults. THAT is a reason to go back a human could empathise with. Anything else is a lie to yourself and others, it is clearly all utter lies and brainwashing.
I hope however that whatever you choose makes you happy, sometimes ignorance is bliss and the difficult decision of choosing ....TRUTH or what's comforting is very hard. Cults depend on it.
