Half Banana - The JW delusion is a psychosis i.e. the holding on to a belief irrespective of sound evidence to the contrary...
Good post. What you described can also be summed up as "faith" - i.e. strong belief in God or in the doctrines of a religion, based on personal revelation rather than good/demonstrable evidence or evidence to the contrary...
Half Banana - The big question is how can JWs or for that matter any other religious person be de-radicalised?
Other posters said it better than I could... The one thing I would add is that we need to improve education and encourage critical thinking to inoculate people who haven't yet surrendered their life to "faith". There are a lot of people living in that bubble (my family included) that may not be salvageable. We should continue to help those still in but also try to proactively inoculate people from going in.
