How's this for a twist on the topic: Yes, I blame my parents (actually my father and grandparents, who raised me) to some extent for my involvement in the JW's, despite the fact that none of them were ever JW's themselves and that I wasn't raised as a JW.
No one in my family ever went to church when I was a kid. I think by the time I was 12, I had been inside a church maybe 3 times, and never the same one twice. There was effectively no religious training in our house as I was growing up, except for the most superficial sort, i.e., 'If you're good, you'll go to heaven when you die, if you're bad, you'll go to hell'. Then there was, 'If you're really bad, the devil might come for you in the middle of the night and spear you on his pitchfork and carry you off to hell right then'. Pretty fearful stuff for a little kid.
Anyway, there was this big fear of God and fear of the devil combined with no religious training and an undeveloped baloney detector. Can you see why, as a teenager, I was a sitting duck for a cult? I tend to think that if I had been raised with even a semi-normal amount of religious training, I might have been able to discern what a load of crap the JW's were pushing.
The reason I was raised by my father and grandparents was that my mother had died giving birth to me. I think that was the biggest tragedy of my life. She was a born-again Christian, a Methodist, and a Sunday School teacher. She was also, from everything I can gather, a normal young woman. I think she would have been a healthy influence on my life, had she lived, and that she would have provided enough training in the Bible and religion so that I wouldn't have felt a big spiritual emptiness as I entered one of the most impressionable periods of life. Also, I think she would have taught me enough of the Bible that the JW's wouldn't so easily have pulled the wool over my eyes.
And when the time came for normal teenage rebellion, I'd probably have rebelled by sowing wild oats like a normal kid instead becoming a cult zombie. Not that I'm saying that everything I would have done in that case would be something I'd condone now, but, frankly, I think that direction is mentally healthier than being a JW. Besides, I'm sure I'd have grown out of it after a few years.
So there you have it. I don't hate the memory of my father and grandparents; I've long since forgiven them for the dysfunctional setting I was raised in. But the question was whether I blame them, and, yes, I see no alternative to laying at their feet a lot of the blame for my ending up in a cult.
