It also manifests in this sort of insulted vibe that religious people get when their faith is questioned.
Basically, it’s socially not okay to question the faith of someone in a particular religion because it’s their culture, it’s their belief system, but the atheist/agnostic “belief” system isn’t respected in the same way. The person who has not found any evidence of god as described in various religions is told to seek enlightenment as if they are the ones who are incomplete.
People who use the scientific method don’t “pick at random” when there is no available answer. They test for answers and wait until they observe the answers and have the ability to reproduce those observations.
In short, the religious expect the non-religious to be afraid of dying and to be looking for a solution, when it’s completely valid and logical to have determined that there is no solution and therefore it is not worth spending time dwelling upon.
