A meta-followup to this example question:
Keeping in mind that language questions with a buddhist connection (e.g asking for the meaning of a word used in buddhist scriptures) should be 100% fine...
What about questions that rely heavily on knowledge of buddhist traditions to explain the language aspect, e.g.: "What is the nuance between kanji/words X and Y in buddhist culture?"
Japanese buddhist terms do constitute a whole sub-section of the Japanese language. I think such questions should be fine, but thought it would be worth discussing and addressing explicitly (even though I honestly doubt we'll be overrun any time soon).
If we allow them, does anybody have anything against the creation of a buddhism tag?
