Yes, you are invoking indigenous cultures as a stand-in for state of nature, to imply ethical or moral consideration of the well-being of animals is somehow de facto off the table, which is obviously absurd.

I haven't said anything about "indigenous culture."

I grew up in a rural settler society. We recognize that invasion fish, brought by international trade, are extremely detrimental to our ecosystem. We need more people fishing & consuming these fish to slow down ecological collapse.

We also recognize that human activity is causing the extinction of vulnerable species & predators, the rapid boom white-tailed deer population. We need to intervene to protect vulnerable species, which includes more hunting white-tailed deer to slow down their dominance over all natural food sources.

These are examples of humans, in industrial societies, needing to perform the role of predator in the ecosystem. And I haven't even gotten into husbandry relations.

why are you so absurdly defensive that you keep insisting we can only talk about indigenous cultures when talking about vegetarianism or veganism

I have not limited this to indigenous cultures. The problem is that veganism does not make much sense outside the context of mass industrially produced animal products. And the root of the problem there is our alienation from nature.
