Forgive my ignorance, but what is the difference between an Eskimo and an Inuk? That said, is "Eskimo" derogatory? I live (well south of you) in New York, and many of my peers refer generally to northern Canadians as "Eskimos". I know that isn't right. Can you (or someone else) elaborate? In my opinion, I feel like "First Nations people" is appropriate, but to be honest, I'm talking out of my ass. Can you school us, or at least me, in this?
