Opposition to Eugenics

Some scientists became skeptical of eugenics as time went on, but much of the opposition to eugenics came from traditional religious communities, especially Catholics and some evangelical Protestants. In 1930, Pope Pius XI issued the encyclical Casti Connubi, which condemned eugenics. By contrast, more theologically liberal clergy often supported eugenics.
