Almost every time I've seen it in action, it felt like an Onion-grade parody, the same grade of stuff as the white people complaining about tribes in Canada building malls and housing towers and not living like historical stereotypes instead (https://www.cbc.ca/newsinteractives/features/land-back-podca...).

The one exception was a traveling theater show with Native peformers and no actual control over the theater, and even then there was some careful rhetoric involved to keep it from sounding like an accusation aimed at the audience.
