Answer:
Step-by-step explanation:
Eugenics was used to justify the following:
1. Selective breeding: Eugenics promoted the idea of controlled reproduction, advocating for the selective breeding of individuals with desirable traits while discouraging or preventing those deemed "undesirable" from reproducing. This approach was used to justify the belief that human populations could be improved by promoting the reproduction of individuals with favorable traits and discouraging the reproduction of those considered less desirable.
2. Sterilization and involuntary contraception: Eugenicists justified the forced sterilization or use of involuntary contraception on individuals considered unfit for parenthood. They argued that by preventing certain individuals from reproducing, the overall quality of the population would improve.
3. Immigration restrictions: Eugenic principles were also used to support policies that aimed to restrict or control immigration. Some proponents of eugenics argued that certain immigrant groups were genetically inferior and posed a threat to the "racial purity" or genetic quality of the receiving population. These arguments were used to justify the implementation of strict immigration policies.
4. Discrimination and segregation: Eugenic ideas were used to justify discrimination and segregation based on perceived differences in genetic traits. This included policies and practices that targeted individuals or groups based on their race, ethnicity, disabilities, or other characteristics deemed undesirable by eugenicists.
It is important to note that eugenics has been widely discredited and is now considered unethical due to its association with discrimination, human rights violations, and the misuse of scientific knowledge.
