Native Americans? Due to genocide and imperialism their societies may not look the same as they did centuries ago but they still have tribal identities and culture. After murdering them, robbing them of rights, and continuing to practice discrimination against them, it's a little awful to take symbols and stereotypes associated with them, remove the human element, and stick them on monsters.
What good are technical advancements if they come with oppression and exploitation? Why does "less technically advanced" always equal "less fortunate"?
