Tom Buchanan is supposedly reading a book called “The Rise of the Colored Empires,” which is a reference to the real-life book The Rising Tide of Color, by Lothrop Stoddard. Stoddard was a white supremacist and Buchanan’s association with his ideas–in particular, the notion that northern Europeans have contributed everything that makes civilization worthwhile and must guard their dominant position vigilantly–is likely to make Tom unpopular with readers.
