I have seen so many that have left. And their life turned into a dumpster fire. Most do not live the average life of living in suburbs, raising a family. And such. And then the organization uses such ones as examples of what happens when you leave Jehovah. Thoughts?
What some people don't seem to realize is that not only the WT brainwashes people to control their lives as JWs, but also convince them of what they claim awaits them if they leave. Some JWs, especially those who get disfellowshipped or leave abruptly for any other reasons, don't prepare themselves for their lives outside.
They don't limit their indoctrination to how their lives as JWs should be, they also teach that if you leave, you are supposed to be this, become that, or this will happen to you.
Furthermore, some people end up joining religious organizations and/or cults precisely because they lack the life skills to negotiate with their own lives, hence, expect their god to make things right for them and take care of them. When they find themselves without the cushion of religion, they don't know what to do with their own selves or their lives.
Not everybody can face the ugly things in life and have the skills to properly cope and have a sense of making it on their own.
