I have not seen the movie. I see very few movies.
Native American is a term much improved from Indian but still so weak and uninformative. I worry much that the world only sees the Plains Indians from central North America and does not understand about all the rest. Even myself who cares and is slightly aware knows very little about the other “Native Americans.” I was in the Playa Del Carmen area of the Yucatan and it woke me to how wrong I often am. The people might be Mexican but that does not mean they are Hispanic. They might me Mestizo but so many of the people around me seemed more likely to have no Spanish heritage.
I can just imagine some of them at the U.S. border or in the U.S. and because they came from Mexico, they would be labeled Hispanic.
Farther south, say in the Amazon. Would it be right to call the indigenous people there Native Americans. Well, it would not be a lie but it is so uninformative as to be a hinderance. We know to not lump the Eskimos in with other Native Americans but still that puts the Inuit, the Yupik and the Aleut in a smaller box.
This problem is so broad it is staggering even if it only affects a few people. There were more nations in the Americas than there were in Europe. I think Africa has a similar problem. To much European thinking about Nations as opposed to Peoples.
