60s, 70s and 80s.
That is the age of JWs that are still in, and can't or don't want to wake up.
Because they've given all their life to serve the 10 or more old white men in NY that they've never met. 70-80-90 plus years down the drain and they will never get them back Many of these fellows let their wives die instead of saving them with a blood transfusion. As well as children and husbands who needed one.
There is a few old jws in their 90s that have woken up and posted their experience on reddit, but it's only two or three and they are devastated. One just wanted to commit suicide. Never heard from him again So I think it's better for those jws to never wake up.
And me personally I blame the Bible more than the Watchtower. That book has cause so many deaths through out two millenniums. The Catholic inquisitions cause more harm than the Watchtower because they tortured people who wouldn't accept their "Biblical interpretations for hundreds of years.
The Crusades cause so many deaths of innocent men, women and children.
All religions today are in a competitive race to see who can accumulate the most property with the donations of it's members.
If I believed in the Devil, the bible would be his main book to mislead humanity.
