> Slavery is an excellent cognate to this.
No it's not. I always find the idea that humans are not in some way special (at least to other humans) off-putting. Even animals treat members of their own species generally better than they treat other species.
I love animals, I think we should treat them with dignity and respect as much as possible. At the same time I would not hesitate to kill an animal for food or if it endangered another human.
The cognate here is about how attitudes about systemic actions can change due to a shift in consciousness and access to alternatives. Many people saw black people as not their own kind, and saw no reason — beyond economic imperative - to treat them with compassion.
You said yourself:
>I think we should treat them with dignity and respect as much as possible.
It becomes more possible to treat animals with more respect and dignity every day. For vast portions of the population (Not all! Not yet!) the slaughter of animals for food is becoming less and less necessary.
So the question becomes, given that you believe we should treat animals with as much respect and dignity as possible, do you believe you have a moral imperative to take advantage of these systemic advances?
