People need to be familiar with both approaches. And there's sillyness on both sides. I've seen influential imperative OOP programmers on stackoverflow model a bank account using a single mutable variable, even when they surely know accountants use immutable ledgers. Most imperative languages since Fortran contain declarative elements, otherwise we'd be adding numbers with side-effects. Similarly most FP languages offer imperative programming. But the real power from FP comes from it's restrictions and yes, query languages are one such (excellent) application. Config languages and contract languages are others.
