Alone;
I completely agree with the upper half of your post.
With respect, I disagree with the lower. Beliefs can be, and are often, evolutionary. That certainly has been my experience, anyway! And they evolve based on knowledge aquisition.
However, I would agree that *rigid* beliefs can be dangerous.
Bobby, I'm happy to have helped, and I'm very glad you're here and enjoying it. I think you add quite a bit, too! Thanks for those contributions you make.
Shalom!
