You don't have to , I've read her entire mentally ill history .. She's a Nazi for sure. Brown shirt all the way, ..
If you switched Sangers name with Adolph Hitler's name when reading Sanger's abortion - eugenics philosophy - reasons for self justified killing, you'd think you were reading the same book.
When Sanger wrote and made public addresses about reasons for killing the "undesirables, people not worth of life for reasons ranging to perceived mental illness, dredges of society etc or based on welfare, "unfit parenting" , she thought she had the right to determine who was worthy of the right to bear children. It's the EXACT same things that Adolph Hitler said. You could take either of their names, swap them around when reading about the women's rights - abortion issues, you wouldn't know which one you were reading.
If you read all of things I've posted about Hitler and his Eugenics leaders as to how the abortion agenda should and would be enacted in "enemy nations", then read Sanger's abortion quotes, you would not know which quote belonged to whom.
