I have to agree with smartcooky (unless I have misunderstood?)
Eugenicism is now assumed to be a 'Nazi' phenomenon, but pre WW2 it was a widely held belief both amongst those on the left (e.g. HG Wells) and the right. Many conditions were thought of as being inherited we would no longer consider as such. Even progressive liberal people used language that would be regarded as uncomfortably racist now.
I am uncomfortable about the racist connotations of negro doctors for negro patients, but movements like this and developing negro universities were seen as progessive at the time. Clearly she involved community leaders in her actions which is still advocated.
The concern about people thinking she was promoting a race based sterilisation program is interesting, it is something still raised e.g. with the covid vaccines, that they are intended to render Africans infertile. So ensuring community leaders can address these concerns is still something that would be done.
Sadly it is still true that the areas with the greatest poverty are those with the greatest need for birth control. Options then were of course limited. For a poor working class woman with multiple pregnancies, several children probably in a state of chronic malnutrition abortion may have been life saving for her and her current children.
I am sure that somewhere there are what we would view as offensive statements and racist terminology, e.g. her use of the word negro, but that does not mean she was a proto-Nazi or pro slavery.
