If you, like me, admire H. G. Wells’s futurist novels, you may not be aware of his advocacy of genocide and selective breeding in his “utopian” New Republic. He warned that “whole masses of human population are inferior in their claim upon the future”. “Base and servile types” would be euthanised, including criminals, insane, physically disabled or genetically diseased. “Swarms of black, and brown, and dirty-white, and yellow people, who do not meet the new needs of efficiency, will have to go”

[Anticipations, 1901]
