Almost all writers have heard the phrase “write what you know.” It’s the kind of common sense advice that is too soon disregarded; not that we are to be limited by our experience, but that we should let that experience inform and guide our writing. And if a certain topic lies outside our realm of experience, it is usually possible to expand our realm of knowledge – after all, what else is the internet good for? (Actually, don’t answer that.)
The point is, it can be difficult for writers to force a perspective to which they cannot relate, and stories ought to be at least as varied and diverse as the authors who wrote them.
Unfortunately, that is often not the case.
