Humans have a choice and the ability to consider and reason about morality. It doesn't matter what we technically are, because we have a choice in what we eat and how we treat animals.

Vegan bears and native tribes are irrelevant, you live in a modern world/society and both are poor attempts at deflection that don't hold up under even the slightest scrutiny.

Even if you refuse to consider the argument for veganism, the way we treat the animals we eat is an abject horror, modern animal farming is indefensible.
