Trying to help JWs see themselves by showing them other cults may be effective, but it is is initially met with anger, irritation and suspicion.
I began to see what we really were when I compared us (JWs) to Heaven's Gate (Steve Lett playing the role of Marshall Applewhite).
JW's would never openly advocate mass suicide but they will advocate the refusal to accept a life-saving blood transfusion, avoid formal education beyond high school, and all critical thinking that is not aligned with their narrative.
As a result, millions - yes millions of persons have failed to reach their potential. Millions who used to be living have not caught the comet as they learned that what they were taught was worse than pure speculation - it was a lie. I wonder if they were ashamed as they took their last breath?
