Book review about Margaret Sanger, the founder of Planned Parenthood. She was a Malthusian socialist who regarded poor people as “human weeds” to be sterilized whenever possible. She felt that “the most merciful thing a large family can do to one of its infant members is to kill it.” She was closely connected with the “race purification” scientists of the Nazi party, being convinced that the “inferior races” were a “menace to civilization”, thus, she wanted to create a “race of thoroughbreds.”
