Yeah, to add to your point, not just Christians but also Muslims and basically anyone who believes in afterlife... I think they are not normal for believing in completely unfounded and unscientific fairy tales, but they are likely just as vulnerable as people on this sub. They may have lost a loved one or at a desperate situation themselves, so they are not emotionally ready to rationally argue about afterlife. I believe ai will significantly improve our lives and cure Manu diseases but the singularity will not happen in 100 years at least.
