All religion is not about logic or reason, rather it is about identity. You can join a club for scale model trains, and you can join it for the only reason that you want to and because you enjoy it. You then identify as a member of the train club. It becomes part of your identity.
Religion is similar except it adds a dogma and doctrine that defines your entire world view. To lose this world view is to lose your identity. People would rather die than lose their identity because psychologically one’s identity is synonymous with their life.
The only way a person will lose religion is if they have decided for themself that it’s time for change. Much like an addict, it a personal identity change. You have to say to yourself, I am no longer an alcoholic or I am no longer a Mormon. There is no amount of convincing, rationality, evidence or influence that can change a person until they are ready and willing. It’s transformative and traumatic. You just have to accept those who are lost to it.
