That's clearly not a relevant analogy.

Why does the concept of "ancestral property" somehow suddenly make violence acceptable to you.

Look, it was the person above me who was saying, basically, that it was the miners' violence against the tribespeople that was "acceptable" (paraphrasing, but that's what they basically said). So perhaps you should take up this line of discussion with them, instead.

All I'm saying is - if you knowingly invade territory known to be inhabited by an "uncontacted" community -- that is to say: by definition, a fully sovereign community, and not bound by any treaties with your own government -- and you don't expect the same kind of response (i.e. violent) any self-respecting community would make when not just their land, but their very survival comes under direct attack -- then at the very least, you're pretty damn naive.

And on top of that, it becomes really, really hard to see why you might deserve any sympathy.
