According to Gallup, 32% of Americans (and 42% of American women) consider animals equal to people. I interpret this as meaning “dogs” rather than “animals”, since the vast majority of Americans eat meat. But still, quite an astonishing figure.
Could you see a day, perhaps a couple hundred years from now, where nearly everyone is a vegan and eating meat and other animal products is seen as being just as immoral as we view slavery or genocide today? Will animal abuse and neglect (hell, hunting too) be a crime punishable by death or life imprisonment?
I don’t see humans as being qualitatively different from other animals, but I think we’re so much more complex and probably have a much higher degree of self awareness (though I do think at least mammals and birds have some self-awareness/consciousness). But really intuitively, I think there’s something wrong with elevating animals above people. I’d even save someone I hated over any animal if I had to make a life or death choice. A lot of people view humans as being culpable via free will and animals as being innocent, which probably is part of why there’s a “animals are better than people” sentiment among many, but I don’t believe in free will or that humans can be distinguished from the rest of the natural world.
Then again, I might be on the wrong side of history. I’m sure people made the argument 170 years ago that considering black people equal to white people would be a detriment to the rights of white people. And who knows, perhaps having a less complex brain has nothing to do with how capable of feeling and suffering a creature is.
