Disagreed. My current opinion is that you can be a theist and combine that with pretty much any other knowledge. Eliezer points to Robert Aumann as an example. For someone that has theism hardcoded into their brain and treats it as a different kind of knowledge than physics there can be virtually no visible difference in everyday life from a normal a-theist. I think the problem is not so much the theism, but that people use it to base decisions on it.

There seems to be a common thought-pattern among intelligent theists. When they learn a lot about the physics of the Universe, they don't think "I should only be satisfied with beliefs in things that I understand in this deep way." Instead, they think, "As smart as I am, I have only this dim understanding of the universe. Imagine how smart I would have to be to create it! Truly, God is wonderful beyond comprehension."
