if something as plainly and obviously transformative as the right to vote or the goddamn abolition of slavery don't count as meaningful measures of progress in your eyes, then I don't know what to tell you.
I agree that this country is basically taught to never give a shit about Native Americans.
Giving people their basic rights is not addressing the problem, its acknowledging that was the problem in the first place. Guess what happened after the slaves were freed and got the right to vote? Share cropping popped up, then Jim Crowe laws were introduced and then KKK came about and started killing and intimidating people and so on and so forth. Just because we did the bare minimum after fighting one of the worst wars in our countries history isn't addressing the problem if you ask me.
