Native Americans are still suffering as an ethnicity in the US - while they are free to leave the reservations and won't be punished for doing so, many don't have the means to do so because those means have been taken from them and their ancestors in the past. They suffer from much higher drug use percentage, huge unemployment, and increased crime rates where they live, and that's something that was and is forced upon them.

So no, maybe Native Americans aren't being actively prosecuted for who they are - but they definitely haven't been made whole by the American people.

Again, it's apples Vs oranges. Native American reservations aren't as bad as Uighur concentration camps, but just because it's in the past it shouldn't be ignored. Germany pays wartime reparations to this day, even though they could easily say that Nazi crimes are in the past now.
