Most of them do not want to wake up and here is why.
This religion gives them a sense of importance. The rest of the world does not understand "the truth". Only they do. The rest of the world will be destroyed, only them will survive.
I talked to a friend who does not go to meetings anymore and has waken up. Her sister is a devoted jw. She said that if her sister would see and accept all the facts about this religion and understand that it is not the one and only religion chosen by God, she would probably die in the same day. Her life has no meaning and no sense outside of this religion.
I also tried to talk to some jw's to reason that people will not be judged by the simple fact that they are a part of this organization or not, that other christians in other religions will be saved.
They can not and do not want to accept this. Most of jw's think like this. TheY can not cope with the thought of other people in other religions being saved.
All their feelings and thoughts of self identity and self-esteem are linked to this religion.
