My grandfather was converted soon after he came out to Canada about 100 years ago. My mom knew of the religion through her dad but never took a stand till after she was married. By the time I was born she was a baptised dub. I had no choice as I was dragged to the meetings every Sunday, so that is the only thing I knew. I had doubts at a young age as some of it made no sense. Growing up in the 60's and early 70's I was in the middle of all the 1975 hype. I think looking back I had mentally checked out and started to question the truthfulness of the cult after 1975 but I married into the cult so for the next 18 years I just put on a pretence, going a long with it although my heart was not in it. I was DF'd about 22 years ago and that even though I got re-instated, I have never considered myself as a dub. I do not blame anyone as my parents did what they thought was right. I have never being happier than I am now as I am living life each and every day to the fullest.
So of course the WT Society is right there to offer their scam of imaginary " eternal Life " and imaginary " you'll never die or be sick again " - and people just eat this shit up- I swear. So I think that's what happened to my dad and mom . Now in their early 90's and late 80's they are too invested with my older adult siblings still in the JW cult- they feel they can't leave. And like you I look at my folks situation with pity. Like all of us- they will die eventually , sooner than later - and they were promised they'd never die. One reason I'm constantly calling the WT Society a criminal organization that uses people's lives up, then spits them out and just moves on as a corporate monster. Pretty disturbing. Mind control is powerful. As well as false promises. Lots of JW's and other cults alive and well due to these facts. Peace out, Mr. Flipper
I can relate to what you are saying as this sounds so much like my experience.
