Thank you for the info, but I am quite aware of Margaret Sanger and who/what she was.
It doesn’t change my opinion that what Nixon uttered somehow tarnishes abortion with racism. Abortion tarnishes itself simply being what it is, it didn’t needed any help from Nixon, nor does his opinion make it a racist institution which is what this discussion is about.
I'm not disagreeing with you about Nixon.
But the history of abortion is unquestionably "tarnished by racism" (not to mention a bundle of other moral issues).
