An animal rights advocate based near Washington, DC, Dunayer argues that animals are thinking and feeling creatures, and that humans hide that fact from themselves and inflict cruelty on animals, because euphemisms and other linguistic ploys disguise the abuse. She rings through the various areas in which humans interact with other species, including hunting, sport fishing, zoos, aquariums and marine parks, vivisection, and agriculture and she suggests alternatives to the demeaning terms.
