Again, you keep taking these statements completely out of context.
Take the "extermination quote.
“We do not want word to get out that we want to exterminate the Negro population.” Sanger was aware of concerns, passionately argued by Marcus Garvey in the 1920s, that birth control was a threat to the survival of the Black race. This statement, which acknowledges those fears, is taken from a letter to Clarence J. Gamble, M.D., a champion of the birth control movement. In that letter, Sanger describes her strategy to allay such apprehensions — because exterminating an entire population was not her goal. A larger portion of the letter makes Sanger’s meaning clear:
“It seems to me from my experience . . . in North Carolina, Georgia, Tennessee, and Texas, that while the colored Negroes have great respect for white doctors, they can get closer to their own members and more or less lay their cards on the table. . . . They do not do this with the white people, and if we can train the Negro doctor at the clinic, he can go among them with enthusiasm and with knowledge, which, I believe, will have farreaching results. . . . His work, in my opinion, should be entirely with the Negro profession and the nurses, hospital, social workers, as well as the County’s white doctors. His success will depend upon his personality and his training by us. The minister’s work is also important, and also he should be trained, perhaps by the Federation, as to our ideals and the goal that we hope to reach. 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” (Sanger, 1939, December).
In fact, Sangers efforts to bring family planning to people of color (because White people already had access) was praised by people like Marcus Garvey and Martin Luther King.
Now, yes, Sanger was a believer in Eugenics, when that was a science that had some credibility and before it was twisted into something truly awful by the Nazis. That has more of a misunderstanding of an incomplete science and a lot less about malice.
