This guy here says it’s not. What a crock.
Hallucinations – the person has invisible friends who (s)he insists are real, and to whom (s)he speaks daily, even though nobody can actually see or hear
Delusions – the patient believes that the invisible friends have magical powers to make them rich, cure cancer, bring about world peace, and will do so eventually if asked.
Denial/Inability to learn – though the requests for world peace remain unanswered, even after hundreds of years, the patients persist with the praying behavior, each time expecting different results.
Inability to distinguish fantasy from reality – the beliefs are contingent upon ancient mythology being accepted as historical fact.
Paranoia – the belief that anyone who does not share their supernatural concept of reality is “evil,” “the devil,” “an agent of Satan“.
Emotional abuse – religious concepts such as sin, hell, cause feelings of guilt, shame, fear, and other types of emotional “baggage” which can scar the psyche for life.
Violence – many patients insist that others should share in their delusions, even to the extent of using violence.
Religion still seems to be the one kind of crazy that is commended, applauded, and not treated.
