I don't care if it's teachings are false, I'd never leave because it's the best way of life.
Hi 4thgen, It sounds like someone has a severe case of cognitive dissonance. They may have serious doubts, but need help realizing that they don't believe the WTBTS.
I would ask them, "What are you afraid of? . . . (pause wait for a response) . . . Are you afraid of being shunned by JW family and friends? . . . (pause wait for a response) . . . Since you don't care if the WTBTS's teachings are false, does that mean that you do not believe that Armageddon will happen? . . . (pause) . . . [Continue asking simple questions to continue the conversation.]" How is their life better? If they were not JWs what would they like to do. Get a better education? Travel? Do a fun hobby?
Peace be with you and everyone, who you love,
