As I said, it would be hard to say what all influenced their decision the most in the end. The problem that they perceived with his religious belief, probably erroneously, is very much about him fitting into the group.
Scientists are not experts in religion any more than most people. It is too bad they didn’t see fit to ask him more about it. But the concern seems to have been as much with the public perception of his beliefs as with what he actually believed. Which is wrong - they should have more moral fiber than that. But my point was that this kind of attitude or perception is very much enabled by people who go around insisting that Christians must reject all serious science. Not that they personally think that this is the best interpretation, but that they MUST. Those people either don’t realize, or don’t care, that they are making the whole problem worse. Because of this kind of frenzied activity against science and especially evolution, many people become convinced that Christianity is a position of the foolish, the uneducated, and A-1 nutters.
I sometimes get the impression that they like that result - they see this as a test of who “really” has faith, and they want to cause this huge social rift between believers and non-believers. And I think that is wrong.
