Do not ask to touch them or their hair.
Do not ask if they have an “Indian name.” Some do but you should not ask someone you just met this.
Do not say “red dot or feather?”
Do NOT call them Pocahontas or Sacajawea. This might make someone want to physically harm you.
Do not call them or anyone else your spirit animal. You do not have a spirit animal.
Do not say that you thought Indians were extinct; this might also result in someone wanting to physically harm you.
