You can’t argue facts and reason with a believer. They are conditioned, even programmed, to regurgitate what they are taught. Belonging to the group makes them feel wanted, even loved, and the alternative seems too unbearable. They are told every Sunday how horrible the ‘outside’ world is and how deprived worldly people are. They are told that they will go to heaven through faith. This is the most important part and so… logic, reason, facts… do not register. In fact they are being oppressed and would actually feel free if they could leave, but they can’t.
