Religion is a Delusion/Mental Illness

[Jenny A]

I don't know about that but it seems a little over the top to conclude religion is mental illness.  I know plenty of people who are theist and entirely rational.  I doubt it.

Lots of people are otherwise rational but delusional on some particular point:  religion, a conspiracy theory, the wonderfulness of their abusive significant other, their talent, their chances of winning the lottery, etc.   But if a person belived in the kind of delusion that is most religions and no one else believed it, it would be considered an mental illness.
