" Those who believe it is immoral to kill animals for any reason, including eating and humane medical experimentation, should reflect on this: While there are strong links between cruelty to animals and cruelty to humans, there are no links between kindness to animals and kindness to humans. Cruelty to animals frequently indicates a tendency toward cruelty to fellow human beings. But kindness to animals does not indicate that a person will be kind to other people. The Nazis, noted for their cruelty to human beings, were also the most pro-animal-rights group prior to the contemporary period. They outlawed experimentation on animals—but performed widespread experiments on human beings. And Hitler was famously affectionate toward his German shepherd, Blondie, while consigning millions of people to hellish misery and agonizing death. "
