What separates us from humans and animals? Well those being argued at the moment are 2 things:

1. Soul
2. Conscious

There is not yet scientific proof animals have either of these. This is the reason why you don't see a bunch of disability children rounded up like animals, because all humans having a soul are equal in the eyes of God, this is the legal argument. Just like beauty is in the eye of the beholder, understanding another fellow human being is in the eye of the beholder. We may meet a man with a cognitive deficit, my background in psych means I can interpret him easily, whereas you may think he's "stupid" or something. So yes from a legal and logical point of view, it is morally wrong to farm humans for food. But, that doesn't mean it's not been happening, cheap labour, test subjects etc. are still happening as we speak.
