What can we truly know about the inner life of another person with any certainty? Not a lot I think.
But it certainly seems to me that many people live their whole lives happy as Jehovah's Witnesses. They have careers, friends, family, a place in the congregation, a sense of purpose, and an ideology that makes sense of the world around them. Sure some leave because being a Witness makes them miserable too. But we should be cautious about assuming our own thoughts and feelings about any given situation to be universal.
And incidentally, although many are happy to get free from the religion, some apostates are by all appearances miserable once they have left. So it works both ways.
Sounds like Watchtower thinking to me! They need to install a revolving door in this religion because the turnover rate is so high. If the Watchtower was a company to work for it would be rated a horrible place to work because if people were happy in it they would stay but there not so they leave. The many you speak of are the ones who are so braindead and overlook everything and are walking zombies. I met plenty guess what by the time there old there so screwed up in the head there not even human. Some leave,lol they are running out of there faster than they can recruit them. Nice apology reading for the Witnesses and how wonderful it is to be there and is no different than any upbringing. Ya right i was raised in the world and the Witneses are a strange bunch indeed. They are barely human there so brainwashed.Any normal person would see it but you must have been raised that explains your comment because you still think like a Witness!
