Individual people having backwards views stemming from generations of impoverishment doesn't justify imprisoning and exterminating an entire indigenous population. That population has an unconditional right to resist their colonization using whatever means are available to them.

I'm stating a moral position here, not trying to argue with you, because you don't actually care about some unique technical specifics in this one situation. You'd be saying the same thing about "this civil rights leader said all white people or bad", or "that escaped slave hurt that poor white family", or "those Indian savages beheaded 100 settler babies" as though any of that justified the generations of colonial extraction that you benefit from. Whatever helps you sleep at night.
