The hysterical kerfuffle over the latest issue of Action Comics, in which Superman renounces his American citizenship, has predictably inspired a huge amount of jingoistic blathering. And of course there have been plenty of calm, well-reasoned rebuttals from people who actually understand the point of the story and who aren't, y'know, morons.
But one counter-argument I've heard around the Twittersphere - partly in jest, partly not - basically amounts to, "Calm down, Superman's not real." There are many valid reasons to reject the anti-Superman screeds, but this isn't one of them. If you believe that fiction has a serious role to play in demonstrating and shaping societal values, then it's perfectly reasonable to be angered by a work of fiction that seems to spit in the face of the values you cherish - or worse, one you once regarded as sharing your values which suddenly seems to upend or reject them.
