She [Margaret Sanger, founder of Planned Parenthood] even presented at a Ku Klux Klan rally in 1926 in Silver Lake, N.J. She recounted this event in her autobiography: I accepted an invitation to talk to the womens branch of the Ku Klux Klan
I saw through the door dim figures parading with banners and illuminated crosses
I was escorted to the platform, was introduced, and began to speak
In the end, through simple illustrations I believed I had accomplished my purpose. A dozen invitations to speak to similar groups were proffered. (Margaret Sanger, An Autobiography, Page 366). The Washington Times, Margaret Sanger, racist eugenicist extraordinaire, May 5, 2014, by Arina Grossu.
