Proud to be
The video described the Native Americans, children playing. Parents holding their daughters and sons. People wearing colorful clothes and feather headdresses. They're riding horses.
Proud, chief, struggling, understood.
The Native Americans are proud of who they are. They have struggling a lot but they're still proud of their backgrounds and their cultures.
I think they need to be treat fairly by other people, they would like to be called "Native Americans".
