Why you should distrust all religions.

[brewer]

I don’t see how the title of the thread, relates to the video. Certainly it doesn’t seem to follow from the video that people who have had a religious experience are mentally ill.

Of course it does!  If I lose my keys, do I just assume that a fairy took them?  How do you distinguish between someone who is a functional schizophrenic from someone who has a "genuine" religious experience?

By diagnostic interview. Not all schizophrenics have religious experiences. If they do, you'll find that the schizophrenic thought process is fractured and tangential with inconsistencies and disorganization. Also the affect will often not be appropriate to the conversation.
