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 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". 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.
