Some people seem invested in the idea that animals are not intelligent, do not have feelings, are not persons etc, despite so much evidence to the contrary. Why is that?
Assuming you're genuinely asking. I believe it's because feelings and intelligence would mean that animals suffer pain like we do, which would imply that we are cruel for eating or using them as we do.
The best analogy I can come up with that many Americans would relate to would be slavery, when slave owners would insist on dehumanizing them. They were both financially and emotionally invested in the idea that slaves could be used and abused.
