Not alone, but as part of a "eugenics" program. Then you take the lists of people she identified as inferior races, including Black people, and the logic is inescapable. Add to this her infamous "Negro Project" and the fact that she concentrated her efforts on opening birth control clinics in Black areas, and there's no escaping the charge.
It seems like making distinctions among evils, but her "eugenics" views were somewhat complicated, and not necessarily identical to nαzι eugenics.
The quote I'm discussing was made in the context of the "Negro Project", I think. The full quote is: "We do not want word to go out that we want to exterminate the Negro population, and the minister is the man who can straighten out that idea if it ever occurs to any of their more rebellious members."
I know some people take this to mean she wanted to hide what she really believed, but it can also be taken as she foresaw a false allegation and tried to take actions to avoid it, by hiring black ministers to be intermediaries with the community. The latter is, I think, the mainstream interpretation, so it's a tough sell to insist that it absolutely must mean she was hiding what she really believed.
