No, humans are enslaving and torturing multiple species because they taste good. And I'm the irrational one? Because I value not causing suffering over personal pleasure? If that's irrational, then fuck whatever is considered rational. It IS morally reprehensible. Just because they aren't human doesn't mean they don't suffer. If there were a group of humans that were perpetually imprisoned, tortured, and eventually murdered, we would call it what it is: genocide. It fits the definitions laid out by the UN.
