Cambridge University Press has an important scholarly book on America's most important racists. Authors Randall Hansen and Desmond King , on page 46, of their book Sterilized by the State: Eugenics, Race, and the Population Scare in Twentieth-Century North America discussing the infamous Margaret Sanger:
Sanger was a key figure in the American birth control movement; indeed , she invented the term. But, Sanger's activism extended beyond enhancing women's reproductive choices to include an embrace of standard eugenic goals: improving national breeding through positive and negative measures. The journal she founded in 1917, Birth Control Review, opened its pages to numerous eugenic advocate articles, some penned by Sanger herself. Her book, The Pivot of Civilization , published in 1922, rehearsed standard pro-sterilization arguments from eugenicists in respect to the feebleminded and others whom she thought ought not to be allowed to procreate. One theme that she emphasized in particular was the dangerous effect of benevolence and charity in helping those whom natural selection processes would have eliminated. This applied particularly to very poor women in urban ghettos who then went on to procreate in a way that increased fiscal charges on the public purse.
