We have but one apologetics tag. This tag is currently being reviewed to clarify its use and intent. The purpose of this qustion (which is related), is to ascertain whether we need a second tag (which kinda depends on what we do with the linked meta discussion).
Proposal: Should we create an apologetics-studytag, which would be a tag for questions about apologetics, meaning they are questions about what Apologetics is, how apologetic arguments are developed, what makes a good apologist. In other words, the tag would refer to the study, field, or process of Apologetics.
Contrast this with the existing apologetics tag, which would be a tag identifying a question as needing assistance developing a specific apologist argument.
