Attempts to find contemporary political meaning in the most popular works of science fiction and fantasy are a perennial favorite on the Internet, even when they get out of hand.
The most reason one seems to be a dispute over whether a post on J.K. Rowling’s blog makes mistakes about political science as it relates to the history of Africa. Timothy Burke, an anthropologist at Bryn Mawr, has all the links here and here; Vox has an explainer here. I like Burke’s, especially, because he goes into what he thinks the differences would be, between an African magical establishment of the kind described by Rowling, and what she describes at Hogwarts.
Attempts to find a philosophical meaning in a book based explicitly on Plato’s Republic are not very surprising. Jo Walton’s The Just City is such a book, and Crooked Timber has a symposium about it.
