I think this is a core question.

I don't believe that religion works if it is sold as a series of fables containing practical advice encouraging pro-social behavior (even if that's how it functions). Religion works as myths that are true and make your hair stand up when you read them.

Most Christians have already shed a lot of now-disproven beliefs. Angels aren't literally flying in the sky over our heads. Literal stories get re-interpreted as metaphors or the definitions of words changed. Contradictions get solved by picking whichever one agrees with the culture at the time. And there are a lot of contradictions, so if logic was enough to un-believe a Christian, they would all have become atheists already.

Most Christians have already became atheists though. USA is lagging the rest of the world a bit, but the trend is clear all over.
