One way to tell if a person is truly an idiot is when you hear this person says: "this is very absurd and untrue, because in my xxx years I never experienced it."
Yeah, you never experience death before, but it doesn't mean you won't die!!!
Many people never live outside their small, tiny circle so that they have no idea of what "good" and "right" thing should look like. When you explained it out of a good will to them, they instead think you are the weirdo.
