Deletion of Exigence (rhetoric)

Comment: or merge to Rhetorical_situation#Lloyd_Bitzer, where the concept is mentioned. Per , don't be fooled by suboptimal writing; this article is about the concept of exigence in the field of rhetoric, not just the term. While it starts out with a definition, as many good encyclopedia articles do, the next section is about the concept, not just the word. Exigence is one part of a rhetorical situation as described by Lloyd Bitzer, a notable rhetorician, along with audience and constraints. I don't know if there is enough sourcing out there for this particular concept to be notable. If not, then a natural merge target would be Rhetorical_situation#Lloyd_Bitzer. But I don't see a valid policy-based reason for deletion
