It is true that Sanger was a proponent of eugenics, and pro-choice advocates do themselves no favors by attempting to whitewash this fact and paint Sanger as some infallible feminist hero. Sanger was passionate about contraception — perhaps to a fault — and her fervor about promoting her birth control agenda led her to align herself with eugenicists, along with racists and an assortment of people of questionable character.
But it is simply untrue that Margaret Sanger wanted to exterminate the Black race. This is a flat-out lie. Yet it is one that is repeated ad nauseam, both by anti-choice activists and the politicians who support them, most recently Ben Carson.
In propagating this lie, anti-choicers infantilize Black women and strip them of their agency: they portray Margaret Sanger’s birth control agenda as something that was done to Black women, rather than something in which Black women and much of the Black community as a whole enthusiastically participated.
