Religion as a mental illness

[brewer]

Then you and I will have different standards on what is considered mental illness and what is acceptable in society. The vast majority of the god delusion people I am not willing to categorize as mentally ill, neither is our society.

Clearly we do, but when differences exist, the rational solution is to actually justify your position with more than an opinion.  How can people who believe in things that do not demonstrably exist, who talk to things that aren't actually there, not be mentally ill?

I have justified my position, you choose not to accept it. Discussion over, solution reached.
