Some of Heinlein's other works have also been described as racist, though Franklin argues that this was not unique to Heinlein, and that he was less racist than the U.S. government of the time. Heinlein's early novel "Sixth Column" was called a "racist paean" to a white resistance movement against an Asian horde derived from the Yellow Peril. In 1978, Moorcock wrote that "Starship Troopers" "set the pattern for Heinlein's more ambitious paternalistic, xenophobic" stories. Robert Lowndes argues that the war between the Terrans and the Arachnids is not about a quest for racial purity, but rather an extension of Heinlein's belief that man is a wild animal. According to this theory, if man lacks a moral compass beyond the will to survive, and he was confronted by another species with a similar lack of morality, then the only possible moral result would be warfare.
