I'd like to replace the current Philosophical/Sociological close reason with one that gets more at the meat of why we're closing the question and offers some help for what to do to fix the question:
General philosophical or sociological questions are off-topic unless clearly asking for a doctrinal answer. See: On-topic and constructive examples
Questions that could be answered from multiple Christian viewpoints are not allowed, unless specifically asking an overview question
The stats show we're tending to favor the "opinion based" close reason, so we might as well revamp the custom close reasons so they don't overlap with opinion based as much.
I'd hope this would fix the qualms of new users who just want to have a discussion about the Bible, but probably weren't expecting to read what Jimmy Akin said Aquinas said Augustine said Paul said.
In the end, I wound up replacing the Truth close reason rather than the Philosophical close reason.
