Uneducated and ignorant people refer to Native Americans as “Indians.” They are not Indians. Anyone who was native to any part of the Americas are “Native American.”
Historically, Christopher Columbus thought he was in Asian. That is why the uneducated Spaniard called Native Americans “Indians.”
Indians are from one place only — India. India is in South Asia.
Anyone who refers to “Native Americans” as “Indians” is a fool, so stop.
