Today's claim that Steve Bannon is a "white supremacist" turns on his praise of a work of speculative fiction, The Camp of the Saints. I have never read this book, so I can neither praise nor condemn it. However, the description and excepts make it sound like it falls squarely within a genre of books that includes some highly celebrated on the Left: The Handmaid's Tale, for example, or 1984, or Brave New World, or Fahrenheit 451.
Each of these includes awful images of a highly undesirable future, for the purpose of criticizing present trends with dangerous conclusions. According to Wikipedia, for whatever that's worth, this piece was written in 1973, and was widely praised by intellectuals at the time of its publication. That it is of lasting interest more than forty years after its original publication suggests there might be something to the book; that it provokes such discomfort among its critics, likewise.
I haven't read it. Perhaps it's awful. Still, what an odd ground for criticism. The quite-Left American Library Association organizes a "Banned Books Week" every year, and maintains a part of its online store devoted to banned and challenged books.
Yet here is the alleged proof of Bannon's evil: "He likes a disapproved book."
