Who even says “Indian” to describe Native Americans anymore?

One of my friends who is also native used that word to describe someone from a neighboring tribe and I genuinely thought he was talking about an Indian as in from India. No one says that for Native Americans anymore, at least not around here! It’s not only politically incorrect, but just plain incorrect. It’s outdated. He as a indigenous person should know that. Say indigenous or Native Americans, but don’t call us Indians anymore. It’s more offensive than being called “red” at this point. 😂
