The Viking vs. Redskin comparison is laughable. If I walked up to a Native American and said: "Hey Redskin!" I'd probably get punched in the face. If I walk up to a Nordic person and say: "Waddup Viking!" he'd probably high-five me. Why? Because to Nords, the term "Viking" is one of pride, they don't look back at their history with disdain like, say Germans with the term Nazi. However, "Redskin" was never created to be a term of endearment, it's existence was solely to denigrate a culture of human.
