It's bad biology to rob nonhuman animals of their emotional lives.
The plural of anecdote is not data.
All animals, including humans, have a right to lives of dignity and respect, without forced intrusions.
Often, the greater our ignorance about something, the greater our resistance to change.
Animals are not property or "things" but rather living organisms, subjects of a life, who are worthy of our compassion, respect, friendship, and support.
Without close and reciprocal relationships with other animal beings, we're alienated from the rich, diverse, and magnificent world in which we live.
