Which is EXACTLY what margaret sangar's intentions were with Planned Parenthood - eugenics.
Eugenics was a discipline, championed by prominent scientists but now widely debunked, that promoted "good" breeding and aimed to prevent "poor" breeding. The idea was that the human race could be bettered through encouraging people with traits like intelligence, hard work, cleanliness (thought to be genetic) to reproduce. Eugenics was taken to its horrifying extreme during the Holocaust, through forced sterilizations and breeding experiments.
In the United States, eugenics intersected with the birth control movement in the 1920s, and Sanger reportedly spoke at eugenics conferences. She also talked about birth control being used to facilitate "the process of weeding out the unfit [and] of preventing the birth of defectives."
