It's not that I don't see anything wrong with it. It's just that it's not a priority for me. I see a lot more wrong with the way people treat people than the way people treat animals, and I don't have headspace for every problem. I guess it doesn't really affect me - out of sight, out of mind?
I know people who treat their dogs like people. Sometimes those same people treat other people worse than dogs. I endeavor to treat people like people, even as I treat my dogs like dogs.
