Once, in vet school, I was accused of anthropomorphizing a dog when I said that I thought she felt sad that her puppies were all taken away one afternoon. "Anthropomorphize" is considered a dirty word by many who work with animals, especially veterinarians. We are not supposed to imbue them with any of our feelings. Why would a dog feel anything, much less sad, that her babies were gone and that she would never see them again?
I was intimidated then. I am different now. Now I know the arrogance of the accusers and that their deprecating word, anthropomorphize, was a way that they attempted to demean empathy. They don't have it, so they mock it.
Many people have compassion. We use the word to denote caring and considerate treatment of animals. I don't doubt that. But you can needlessly kill an animal and say it was done compassionately. You can wrongfully imprison an animal and believe that their care is administered compassionately.You can declaw a cat or test chemicals in a rabbit's eyes and say it is with compassion.
