I did an informal and unscientific poll among First Nations students in my class, both male and female, all over the age of 30. All like the commercial but none thought that the Redskin mascot was offensive. Nonetheless, it is for a significant group of people.
My view is that names such as Braves, Warriors, and so on are empowering terms of honour. Redskin does have a pejorative history. At any rate, good work by the producers who at a minimum accurately characterized the history tradition, and honour of many Native Americans.
