Yes, eugenics is very embarrassing. Eugenics was the attempt to create microevolutionary changes to our species through the means of intelligent design. Embarrassing indeed! :-)Also the term "natural selection" is now preferred to the commonly used term in earlier times, "survival of the fittest," because "survival of the fittest" points toward the Nazis and the eugenists. There is a vast "social Darwinist" literature that cannot be so easily be separated from "scientific Darwinism" as its adherants pretend.
Kill off the useless eaters, the diabetics, and so forth, to improve the species.
