John Gray at The New Statesman:
Awkwardly for today’s secular progressives, opposition to eugenics during its heyday in the West came almost exclusively from religious sources, particularly the Catholic Church. Eugenic ideas were disseminated everywhere, but few Catholic countries applied them. The only involuntary sterilisation legislation in Latin America was enacted in the state of Veracruz in Mexico in 1932. In Catholic Europe, Spain, Portugal and Italy passed no eugenic laws. By contrast, Norway and Sweden legalised eugenic sterilisation in 1934 and 1935, with Sweden requiring the consent of those sterilised only in 1976. In the US, more than 70,000 people were forcibly sterilised during the 20th century, with sterilisation without the inmates’ consent being reported in female prisons in California up to 2014.
