I know that I can not pursuade any member of a group to agree with me
on a subject that threatens to destroy part of that group's belief. I
have anger and have found the perfect forum where I scream, and yell,
and call names knowing that even if I am calm and rational, I will
never get any grouper to agree. So why bother to make an effective
point? No one knows who I am anyway and I won't get a standing ovation.

No grouper, especially religious and 12-steppers, will ever agree with
anyone's beliefs that are different from outside the group.

And quite frankly, I don't think you can challenge that last statement.
After all, isn't all this based on belief and not fact?
