Oh yes, Eugenics. Horrible.But that tendency was by no way an Atheist movement. Please allow me to cite from an article on creation.com:Religious leaders "who became involved in eugenics ‘included Protestants of nearly every denomination, Jews and Catholics, and they overwhelmingly represented the liberal wings of their respective faiths. … They were the ministers, priests, and rabbis who were inspired by the developments of modern science and accepted much of the new historical criticism of the Bible. … Supporters ranged from high-ranking clerics to small-town ministers in the Methodist, Unitarian, Congregational, Protestant Episcopal, Baptist and Presbyterian churches." Citation from Dr Christine Rosen, "Preaching Eugenics: Religious Leaders and the American Eugenics Movement", Oxford University Press, New York, 2004, p 14fTo quote H.L. Mencken: "For every complex problem there is a solution that is clear, simple and wrong".
