Much of sci fi and fantasy is in fact commentary on our current world, often political. Almost everything Ursula Le Guin wrote was political. Kim Stanley Robinson talks fairly blatantly about the struggle against capitalism. Orson Scott Card writes a lot about nation state struggles. Margaret Atwood has a popular, political tv show on right now, watered down as it is, adapted from her very political novels. I don't know how you would describe Cory Doctorow without mentioning political struggle. Alan Moore is very, very political, and should be considered a novelist. And it goes without saying, most influential early sci fi was also political (Ray Bradbury, Heinlein, Asimov, Jack London, Frank Herbert, HG Wells). IMHO this article seems to be more about how the novel has left social consciousness entirely. That's a far less tractable problem than reading the many political novels in print now. Either that or the author is blind to how wide politics can be—pretty much all complex conflict has some political bearing.
