That’s why I said “as a general rule”. I’m not sure I would consider fundamentalists to be representative of your average Christian - their whole thing is Biblical literalism, after all… I was raised Catholic, in an era where we still had religious courses in school, and I can pretty safely say that pretty much nobody read it outside the bare minimum they had to for First Communion/Confirmation/wedding prep.
Oh, that’s for sure. The thing is, you need to be open to the idea that there could be contradictions to realize they are there. If you approach your readings already believing that you are a mere sinner who, in the end, can’t really understand God’s Plan™, it gets easier to brush off the inconsistencies.
