That's history that, at least in my region, we learn about in school. For the most part, we let them do their thing nowadays and aren't actively commiting genocide on them. Police brutality on them may speak differently, but the majority of people who aren't racist and/or rich already want the police gone because of their brutality.

As for the rest of the states, it's a mixed bag due to bad eggs, but I'm fairly certain the official government stance is accepting of the fact we've treated both natives and African Americans bad. It's why we learn about it. Tried looking it up, but was suspiciously finding a lot of content from Chinese embassies in America about how we need to come to terms with the Native American genocides and atrocities, from around the same time as the tribunal, maybe a month or two after people started reporting on it. Very suspicious timing on their part. Couldn't find what I was looking for because I kept getting Chinese (.gov.cn) links over any official US links, which is very suspicious to me because it looks a lot like search result rigging in my eyes.

Edit:

Search result rigging, not search engine rigging.
