You did not. The society that you are a part of did systematically disassemble their society and slaughter any resistance.
So “we” got our trains, oil and highways, and turned the Great Plains into one of the great breadbaskets of the world, at least for awhile. Unfortunately the depletion of the aquifers will leave those same plains a desert from an agricultural perspective in many of our lifetimes. Maybe when that land is worthless to society again the Sioux will get it back.
That or you're just choosing to unfavorably read the word "we" as if it refers to you specifically, instead of to the poster and their cultural, racial or national group, in order to avoid engaging with the substance of their post?
"we"? I wouldn't be so presumptuous.
