Something came up in conversation earlier today, where a friend mentioned that she's heard some people espouse the belief that having a religious viewpoint is literally a mental illness. I don't agree myself; sure, there are a number of crazy religious people, and I think some religions (like most sects of Christianity) should be erased from the world because their worldviews promote insanity. But religion inherently an insanity? No. Anyway, what do you think?
Do you believe that being religious is literally a mental illness?
