A lot of Native Americans hate themselves and ridicule their family, tribe and entire culture. That was the idea from day one. Destroy the culture from within. Make brown people hate themselves. Make people hate their native language. Make brown people hate themselves and wish to be accepted by white people. And once they have destroyed their own cultural connections, then white people say, get the fuck outta here you nigger, you can't ever be like us.
Racism is always a steel toed boot in the face, with teeth and blood and face splattered on the walls of a white room.
