Please understand that I’m not making any kind of criticism of her when I say that JK Rowling has abandoned the real world. When you have one billion dollars, it’s not really something you need any more; there’s no real need to explain why she chooses to live with magic instead. If nothing else, she inhabits herself. In Edinburgh’s rain-splattered streets familiar beings are at work. The troll in chains, for instance, grunting behind the wheel of the bus, pressed into its dreary service shuttling endlessly from Hanover Street to Holyrood and back by a simple first-year spell, Instrumentio, for the manipulation of hyponoiacs – because why else would the Lothian number 6 have ploughed so carelessly into that puddle just as she was walking past? You might think that Ocado being out of smoked salmon for three weeks running is a supply-chain problem, another of those market inefficiencies that together determine the course of our lives, but she knows better: when she scans down her receipt to see it replaced by mackerel again, she knows it’s an infestation of nifflers, scurrying rapacious all along the warehouse floor, snuffling up anything that looks like it might be valuable, cramming thick slices of translucent rippling salmon into their always-hungry bellies. When helicopters thrum overhead to ruin her sleep at three in the morning, JK Rowling knows that a werewolf’s on the loose; when politically engaged young people mass in front of Parliament she sees the crowded hoods of the Dementors, and shivers.

Things continue to work after their usual fashion; it’s house-elves in their willing legions that stitched all her clothes together, and worryingly megarhinic goblins judiciously sliding banknotes to her through the cash machine. She’s grateful for the advice of Hagrid and Dumbledore and all the others as they follow her around this greyed-out half-world, she’s glad that she’s not like all the boring and stupid people, that she has an active imagination and a rich inner life. Of course she knows that all these wizards and griffins are just stuff that she made up, that none of it is really real, that she prefers living with them because she can control it all to the last detail, while even one billion dollars won’t let you rearrange the universe at will. But things aren’t always so clear. She’s sure, occasionally, that Harry had always been there, telling her what to do. He told her to write the book. Then she went back into the house and wrote, It was nearly midnight, and Harry Potter was lying on his stomach in bed. It was not nearly midnight. Harry Potter was not lying on his stomach in bed.

This is about JK Rowling’s political interventions, of course, her pathological tendency to justify vague and insipid reaction by pointing out that some fictional wizards she thought up inside her own head also share her views, her apparent inability to think about the real world without first mapping it onto the one she invented. JK Rowling has variously pissed off Scottish nationalists and the Palestine solidarity movement and the Labour left, wielding a Dumbledore hand puppet that repeats everything she says in a slightly lower voice, but she’s also pissed off a significant number of her own fans, and that’s where you have to start.

In 2007, Rowling was widely celebrated for announcing that her character Dumbledore was gay, despite the fact that there’s nothing to suggest this in the text itself, where she had an opportunity to actually advocate for queer issues; this year, when she told her fans that their personal theories were all incorrect and another character, Sirius Black, was not gay, they were outraged. We grew up with these characters, they insisted, we decide how to read them. JK Rowling is over, they declared, as if she hadn’t already been dead since Barthes. (Or longer: there’s a reason every testament is final, why God never actively intervenes in the world once His holy book is set down, why the medieval Kabbalists had to invent reader-response theory and the Catholic Church headcanons.) What’s clear is that absolutely nobody involved has ever read a word of Derrida.

There are many definitions of deconstruction, none of them particularly good, but you could do worse than to describe it as a mode of reading that refuses to forget the textuality of the text, the fact that it’s a series of marks on a material substrate that were written and which can be read, copied, misunderstood, ignored, or destroyed, that before it conjures up a private universe it exists as a shared object in this one. As a sop to her LGBT+ critics, Rowling shortly afterwards revealed that in her books lycanthropy is actually a metaphor for AIDS. Her position on all this is clear: she came up with these stories, she owns them, and long after they’ve slipped into the wider discourse they still remain essentially hers, essentially private. On Twitter, her header image was briefly two lines of text reading ‘I know what Dumbledore would do. Deal with it.’ The true text of Harry Potter is not on the printed page, but between her ears, to be altered whenever she wants; in her Platonist cosmology fictional events have a shining reality that is all their own, which emanates from out her mouth. She’s following the fandom-headcanon model of literary theory, but here hers is the largest, most bloated head, and the only one that counts. It’s impossible to read this denial of the text anything other than an abrogation of her rights and duties as an author. Sometimes dedicated fans whip themselves up into such a frenzy over their favourite culture-commodities that they act as if the stories were real, centring themselves in a private world that does not belong to them, and JK Rowling does the exact same thing. As soon as she moves to keep hold of her creation, it gains a terrifying, spectral autonomy. JK Rowling is not the author of the Harry Potter books; she is their biggest fan.

It’s in this context that Rowling’s bizarre forays into politics, her marshalling of the powers of literary enchantment for the most banal and miserable of mundane causes, start to make a kind of sense. When she stridently opposed the academic boycott of Israel called for by Palestinian civil society, she did so through a lengthy exegesis on the moral message of her own books, eventually concluding that BDS is wrong because the magical wizards wouldn’t like it. (To be fair, she admits that Harry might have started out with natural pro-Palestine sympathies, but maintains that by the end of the last book he would have grown up and learned to accept that Israel has a right to exist.) When Britain voted to leave the European Union, her public response was that she’d ‘never wanted magic more,’ presumably so she could cast a spoiling spell on millions of ballots. Her opposition to the leadership of Jeremy Corbyn seems to be based on the usual confused half-ideas about electability, as if the party’s right wing and its generic brand of watered-down Toryism hadn’t shown itself to be a losing proposition twice in the last decade, but it’s mostly supported by the fact that, as she insisted, ‘Corbyn. Is. Not. Dumbledore.’ Which is true: Jeremy Corbyn simply isn’t as good as the wise old magician who doesn’t exist, having shown himself to be entirely incapable of casting even the most basic of spells, and utterly failed to function as a universally adored avatar of infallible good; he’s capable of occasionally holding views contrary to those of JK Rowling even when she doesn’t want him to, and he didn’t even have the good grace to give her one billion dollars. None of this is, strictly speaking, analogy; in almost every case she’s responding to other, lesser fans to say that their analogies are inadmissible. In analogy a fictional scenario acts as a map for real events; something intersubjective and mutually agreed upon can explicate (or, if you know how to do it right, confuse) an objective situation. For Rowling, the situation is reversed: real events are trespassing on her characters, the real world is only an imperfect map for Harry Potter.

Rowling’s politics didn’t create those of the Harry Potter fantasy – she is, remember, not an author but a fan. Instead, the books themselves distilled all the latent fascism out of the political mainstream, boiling the discourse into a heavy green slime, and she drank it all down in one gulp. People sometimes try to play a fun game in which they match the Hogwarts houses to political ideologies, usually ending up with a ranked list of what ideas they like and don’t like (Gryffindors are nice social liberals like me! Donald Trump is a Voldemort!). This is the wrong way of looking at it; any division into types must itself exemplify a particular type, so that the four together express a single Weltanschauung. Gryffindor are fascists according to fascist ideology itself, the ideal-ego of the fascist subject: a natural elite, strong, noble, honourable, yellow-haired, and respectful of difference, but only within strict limits. Slytherin is the same figure as she appears to the outside world, her negative aspects projected onto a despised other. Hufflepuff is the fascist’s ideal ordinary political subject, dull and stolid, but essentially good-hearted; Ravenclaw is the indeterminate other that resists assimilation into this conceptual matrix, the thing that constitutes the order through its exclusion, the figure that in the early twentieth century was identified with the body of the Jew.

Harry Potter is a profoundly reactionary fable; its fantasy isn’t really about dragons and broomsticks but the tired old fantasy of the British class system. Harry Potter is the petit-bourgeois boy who goes to a magical Eton (one that, incidentally, runs on actual slave-labour), faces a few tribulations along his way, but eventually finds himself admitted to the ranks of the aristocracy. The central moral dilemma is one of inequality – what do you do when you have one class of people who, by dint of their extraordinary powers, are innately superior to the society surrounding them? (This goes some way to explaining its popularity: Harry Potter is a book for people who are very pleased with themselves because they love books and love to read, without any judgements on what’s being read; it was never for children and always for the bored 29-year-old human resources workers they would grow into. To read Harry Potter uncritically is to adopt the posture of a Hufflepuff.) The crude, cartoon fascism of Voldemort and the Death Eaters answers that they must rule, killing and enslaving the lesser races. The good characters, meanwhile, want the wizarding world to coil up into its own superiority and seethe in its own ressentiment; every adult is seemingly employed by a government bureaucracy whose sole purpose is to maintain a system of magical apartheid. But remember that these are not actually opposing factions, only varying perspectives of a single ideological object; the difference between Dumbledore and Voldemort is as illusory as that between white nationalism and white supremacism. When JK Rowling announces what Dumbledore would do, she’s announcing the politics of the entire work, its good and evil figures all rolled into one. This is what fandom-hermeneutics fails to understand: you can’t introject a single character sliced off from its text; you can only swallow the whole thing. When JK Rowling ventriloquises her friendly wizard to say that Palestine solidarity or socialism make the Hogwarts man feel very sad, watch her head spin round to reveal the pale leering mouth of the Dark Lord.
