On whether I am rational or not, I'll just say this: Einstein believed what I believe. Newton believed what I believe. That doesn't mean I am right but I am certainly in good company.
No, they did not [1] [2]. The two believed such diametrically opposed things that I can't believe anyone could claim to be in the company of both at the same time.
Please leave the condescension at the door. It does not reflect well on your beliefs.

“For me the Jewish religion like all other religions is an incarnation of the most childish superstition… As far as my experience goes, they are in fact no better than other human groups, even if they are protected from the worst excesses by a lack of power. Otherwise I cannot perceive anything ‘chosen’ about them.”
It's always been my experience that motivation depends on the spirit you can manufacture in yourself.
