Nationalism Smashionalism

Thanks to Evie for pointing out this riposte from Michael Lista, responding to Ken McGoogan's call for nationalist determinism in literature. I always wonder when I hear such silly things: how do you assign a nationality to a book set in a fictional place? Why do so many people insist on yoking literature to geography? In McGoogan's case, it's fairly easy to understand why: he writes historical/geographical non-fiction.
