In 2023, the US government returned the remains of some children who were sent to the boarding schools (it's still ongoing). Aside from the bones of children, there were also animal bones. Why were there animal bones mixed in? Because the children's remains were pulled from where the school's rubbish was buried. Separating the bones after all this time would be difficult.

I can think of no better reflection of how the US government treats indigenous people wherever it encounters them. Indigenous Americans have probably received some of the worst treatment. As always, actions speak louder than words.

If you had actually ASKED the Sioux of the Black Hills about this, you'd know they've told pretty much everyone "yeah we don't like Mt Rushmore, we don't like Crazy Horse's relief carving either, but we think destroying them is more disrespectful than just leaving them to fall apart on their own." Like, this isn't an uncommon thought. It's just more complex than "blow them up".
