Argument: Eating and hunting of animals does not justify testing; equally wrong
"When Animals and Humans Are Coequal". New York Times letter to the editor. May 14, 1988 - "Mr. Leff tries to subvert Mr. Regan's invocation of 'respect for the rights of higher life forms' by boiling his concern down to the issue of experimentation on nonhuman mammals, many of which we now eat, hunt or exterminate without undue moral outcry. In reality, those who campaign for better treatment of animals make no such distinctions among the various uses humans make of nonhumans that may cause pain and suffering.
The goal of the humane community is to create a completely new ethic for relating to the other sentient life forms who share this world with us. As editor of the nation's leading animal rights publication, I can assure Mr. Leff that animal experimentation is merely one of the many issues grappled by animal advocates. Of equal importance are the areas of factory farming, dog and cat overpopulation, captive wildlife, humane control of nuisance animals, trapping, hunting and other blood sports - all in addition to a serious and substantial interest in human rights."
