...on Animal rights and the Holocaust:
Several writers, including Jewish Nobel Prize laureate Isaac Bashevis Singer, and animal rights groups have drawn a comparison between the treatment of animals and the Holocaust.
The comparison is regarded as controversial, and has been criticized by organizations that campaign against antisemitism, including the Anti-Defamation League (ADL) and the United States Holocaust Memorial Museum.
Singer described the treatment of animals by humans as "an eternal Treblinka." J.M. Coetzee, also a Nobel laureate in literature, compared the Nazis' treatment of Jews to methods used by the meat industry to herd and slaughter cattle. The comparison began immediately after the end of World War II, when Jewish writers recounted the lack of resistance by European Jewish victims of the Holocaust, who were led to their death as "sheep to slaughter."
Jewish author Isaac Bashevis Singer, who received the Nobel Prize in Literature in 1978, made the comparison in several of his stories, including Enemies, A Love Story, The Penitent, and The Letter Writer. In the latter the protagonist says, "In relation to [animals], all people are Nazis; for the animals, it is an eternal Treblinka." In The Penitent the protagonist says "when it comes to animals, every man is a Nazi."
Edgar Kupfer-Koberwitz, a pacifist, conscientious objector and Holocaust victim who was sent to Dachau for "being a strong autonomously thinking personality", wrote in his "Dachau Diaries" (kept at the University of Chicago Library) that "I have suffered so much myself that I can feel other creatures' suffering by virtue of my own". He further wrote, "I believe as long as man tortures and kill animals, he will torture and kill humans as well—and wars will be waged—for killing must be practice and learned on a small scale".
Belgian writer Marguerite Yourcenar also made the comparison. She wrote that if we haven’t accepted the inhumane transportation of animals to the slaughterhouses we wouldn’t have accepted the transportation of human being to the concentration camps. In another article, making the same connection, she wrote that every act of cruelty suffered by thousands of living creatures is a crime against humanity.
J. M. Coetzee, who received the Nobel Prize in Literature in 2003, invoked the image of the slaughterhouse in describing the Nazi's treatment of Jews: "... in the 20th century, a group of powerful and bloody-minded men in Germany hit on the idea of adapting the methods of the industrial stockyard, as pioneered and perfected in Chicago, to the slaughter – or what they preferred to call the processing – of human beings.
