Girodarno,
I see where you are coming from. To add to what you stated, in particular...
"...it is that semi insane people can and do have a profound effect on the general public if they can present themselves as totally sane."
I can't say there isn't evidence of this as one could argue that this describes Jehovah's Witnesses.
But it doesn't have anything to do with Judaism and its Scriptures, unless you are saying:
There is empirical evidence that the Jewish authors and redactors of the Hebrew Scriptures were insane. I think it would be awesome if you can present evidence that these people were insane because then, at least, we would know who wrote and edited these volumes. Most of the Scriptures were composed by anonymous authors, let alone that we equally have no idea who the redactors were. None of the books fell out of the sky or even off a writer's desk in the form we have today, so this would be an awesome first step in learning who wrote what, despite the fact there were "mentally diseased."
There is such a thing as "semi" insanity. I was unaware that being just a "little" insane meant that part of you wasn't, or does it? If semi-insanity exists, how does the other part of a person remain unaffected, especially when, as you say, the same "semi-insane" people can have such a "profound" effect on others? Your partial insanity can profoundly affect others who are sane but not have enough effect to change you, a semi-insane person, and make you totally insane?
It is more insane to write false stories than to attribute reality to them and base a religion on them. I know this is going to insult some people, so to show it's not my own view I'm going to quote the musical The Book of Mormon: "Wow! God says go to your own backyard and start digging? That makes perfect sense!" I think the actual Book of Mormon is totally false, but I am not sure this means Joseph Smith was insane. I think it says more about you and your sanity if you believe "that ancient Jews built boats and sailed to America," to quote another song from the musical.
Okay, I know that you weren't necessarily writing this to counter what I wrote. In fact you were generally agreeing with some of what I said, it appears. But the report, despite being produced by "sane" and "expert" individuals, still argues an illogical point: blame fiction for your own stupidity of believing the same fiction was real (which you did despite the fact that the culture that produced and uses the very same fiction told you not to take it literally).
After all, who is the real "insane" one? The person who tells you that "God lives on a planet called Kolob," or the person who believes it?
