It's possible to read your comment as the old trope of, if other animals kill to live why can't we? Well I'd be surprised if you'd argue that one person killing another over a personal grievance is the same thing as committing genocide on purpose. Yes both involve the killing of humans, but there are some substantial qualitative differences.
I purposefully talk about industrial scale animal use. It's something completely different for indigenous people to hunt and use animals. The latter I have no moral objections too.
