There are certainly people for whom politics is not a category that helps you understand human existence. In fact, it's kind of a detour into superficiality, and although I disagree with those people, I don't think it's the case that everyone who writes has to write politically or has to write in opposition to the really horrendous things that are going on on a political level in the world today. There are some writers who simply aren't any good at that and really should stay away from it.
