What Do You Mean, It’s Not Political?: It is, I suppose, only in the generic sense of fiction featuring utopias or near-utopias, which is to say, only insofar as it’s therefore automatically a Take That to all those other, lesser, civilizations.
As for more strictly political issues: well, if you’re willing to draw moderately inexact analogies, the Isliar Primarchy is a Take That to traditionalist conservatives, the Magen Corporate to corporatist conservatives, the Annik Sodality to liberals, the Voniensa Republic is one to moderates/statists, the People’s State of Bantral and the Equality Concord to communists (more anarchic and more static, respectively), the Iltine Union to fascists, the Theomachy of Galia to half the Middle East and arbitrarily-selected other religiously-dominated states, Valturak and Nal Kalak to warlordism, the Rim Free Zone to anarcho-capitalists and especially dogmatic Rothbardians, and every single-system backwater polity ever to humanists and Luddites. (Feel free to select whichever combination of acknowledgement and/or ignorance will produce the spin you want on my personal opinions.)
political scientists clionomists have a The Reason You Suck speech ready for all of these, and by extension, for just about everybody on Earth with a political opinion at all. Which is appropriate, since by and large, that everybody has a loud and profoundly ignorant reality-immune political opinion is one of the major reasons why, to steal a perfectly quote, it would be their considered opinion that “All you of Earth are idiots!“
