Have you been practicing good racial hygiene?
"As confidence grew in many places that heredity was a fixed quantity at birth which determined a large range of human behaviors, eugenics societies began to be formed, some with the goal of pursuing scientific investigations of genetics in a ascholarly and scientific fashion, others to discuss and promote new policies and even legislation in support of eugenic ideas. The first was the German Society for Race Hygiene, founded in Berlin in 1905; then came the Eugenics Education Society in England in 1907."
