2008_08_dog1.jpgAn author of a twenty-year-old book that drew parallels between modern day animal cruelty and the treatment of slaves is suing PETA over their tasteless demonstration of the same concepts. Marjorie Spiegel, author of "The Dreaded Comparison: Human and Animal Slavery," says that the animal rights group used materials from her book without permission in a 2005 traveling exhibit that drew significant criticism from civil rights groups. The exhibit juxtaposed images of oppression against black Americans with images of dead, dying, or captive animals. Spiegel’s lawsuit that says PETA’s exhibit has “degraded and impaired public discourse” and that readers of her book are now “forced to view it through the distorted prism that PETA has created.”
