I have included one from the Indiana Evening Gazette dated October 26, 1950. Note two things about this article. First, it is long after the atrocities of the Nazis were known. Second, the name of the organization had been changed to Planned Parenthood - that is, it had already become the organization that it is today.
I have highlighted some passages in the text below. Keep in mind as you read this that it is from 1950. Finally, especially note the last line of the article.

Birth Control Measure Asked by Mrs. Sanger
New York Oct 26 - (AP) - Mrs. Margaret Sanger, founder of the Birth control movement, proposed yesterday that the Federal government provide for sterilization of the feeble-minded and victims of transmissible, congenital disease.
Her message was read to the annual luncheon of the Planned Parenthood Federation of America, of which she is honorary chairman.
"While our present Federal government Santa Clauses have their hands in the taxpayers' pockets," she said, "why not in their generous giving mood be constructive and provide for sterilization as well as giving a pension, dole - call it what you may - to the feeble-minded and the victims of transmissible, congenital diseases?"
"Such a program would be a sound future investment as well as a kindness to the couples themselves by preventing the birth of dozens of their progeny to become burdens, even criminals of another generation. It would save innocent children from the cruelty of being born to such parents."
Mrs. Sanger said that the federation should "stress quality as a prime essential in the birth and survival of our population."
Go hit Planned Parenthoods site as well, where they try to whitewash these views and claim that they are all made up by anti-choice fanatics. The memory hole is here. Thank God for the internet... for now.
