Deletion of Abstract nonsense

Comment: I would not say this article is well written, but that has nothing to do with whether it should be deleted or not. "Abstract nonsense" is a widely used term in mathematics, and its usage is very well attested. As Katzmik points out, it doesn't just refer to category theory, and these days it is hardly derogatory - it is even used with some affection, and not just by category theorists. I've no idea what "useful" is supposed to mean in the context of deciding whether an article is encyclopedic, or how it pertains to any criterion for deletion from, say, . Please remember that Wikipedia's coverage of mathematics is not limited to mathematical coverage of mathematics. Just because it is not a mathematical term with a precise definition does not mean it is unencyclopedic. The term is an important part of the sociology of mathematics if nothing else
