There certainly seems to be a strong correlation between religion and insanity. I’ve read a few papers comparing the logical and psychological aptitude of strong believers vs those with little or no faith at all, and the trends there all seem to be in our favor, but not to the point that religion causes the disorder. I think certain mental disorders can prompt religious beliefs, but that’s a different claim. I think religion provides a haven to conceal quite a lot of cognitive and psychiatric disorders as well as some social dysfunctions. But that doesn’t mean religion is a mental illness, regardless how accurate analogies of the God virus might be. I think there are circumstances when religion can be treated as a psychological condition, especially when it is the result of detrimental conditioning, but I wouldn’t confuse that with a psychiatric malady, which (I think) would have to be physiological/chemical.
