NYT: Charles Patterson’s “Eternal Treblinka: Our Treatment of Animals and the Holocaust” mines another human tragedy for comparisons to animal husbandry. The “eternal” of the title hints at one difference between the Nazis’ attempted eradication of Europe’s Jews and the raising of animals for food — the latter is an ongoing cycle of breeding and killing and not a hate-fueled extermination campaign — but genocide and animal farming can both involve objectification and efficient mass killing.

Some animal rights activists also compare dairy production with sexual assault, because cows are often artificially inseminated to get them pregnant and continuously lactating.

Such analogies are shocking. But are they sound?
