MmeBucket, what you have said are mostly why I disassociated. Especially the Deut. scripture and all the various predictions of The End. Things were always changing and everyone else just seemed to swallow it whole. I couldn't so I left before I was disfellowshipped. (I also had to much of that pesky, worldly education.) It took me ages and ages to lose the fear, though, especially the fear for my kids.
if anyone is looking for silly examples of doctrinal changes: it used to be that you weren't allowed to clink glasses in a toast because that was linked to spiritism (making noises to chase away evil spirits), then it became a matter of conscience, don't know what it is now. It was also not allowed to say "bless you " or the lie when someone sneezed for much the same reasons.
The rules governed even the minutiae of your life and breaking any of them, even the small ones like above would get you a hard chat from the elders.
SGK, yes, I remember the internet being EVIL, as well. WE were all told not to use it because it would lead us into apostasy and sin because we would be unable to resist the Devil leading us to read false religious material. It would also lead us into to sexual sin and immorality because we would be continually exposed to porn/sexual references, smoking, drinking, drugs and other worldly stuff.
When I was active, there was a new anointed (they were still teaching that all the places had been fulfilled years ago). it caused a bit of a stir and a lot of speculation and gossip about who had fallen away. Turned out that it was one of the GB, but it was all very hush-hush.
The other reason that I left was, frankly, the absolute lack of grace and forgiveness. The girl who converted me was disfellowshipped when she was in her 30's, basically for having a nervous breakdown.
She had been a pioneer since she left school when she was 16 (as was encouraged then, particularly for girls.) In her late 20's she started courting a JW man, but her family and the elders felt that he was unsuitable for her. He was much weaker in "the Truth" than she, apparently. So she was hounded and badgered: elders coming to her house, sending for her to go to meetings with them, phoning her.....all to try to persuade her to stop the courtship because it endangered her eternal life (and their recruitment figures) because he wasn't "strong enough in the Truth" and bad associations spoil useful habits. Eventually she had a breakdown through the whole thing. She was disfellowshipped and lost everything, even her home because she house shared with other pioneer sisters. She had no qualifications and no work experience because she had been in the work full time for years, so she couldn't get a job, even when she was better. She lost all her friends and family, everything. It was absolutely awful.
