Nazi eugenics
After World War II, the idea of "racial hygiene" was not promoted. The racialist ideology was denounced as unscientific by many, but there continued to be supporters and enforcers of eugenics even after there was widespread awareness of the nature of Nazi eugenics. After 1945, eugenics proponents included Julian Huxley and Marie Stopes, but they typically removed or downplayed the racial aspects of their theories.
