Someone didn't do enough research. "Indian" is used today in the US media to mean "Indigenous Person". Living in Canada, I found it confusing because  I thought it meant "Person from the country of India". I am a "Yankee" or a "Yank" and I didn't know I was supposed to take offence when I was called one. And I sure didn't know that both "N" words are taboo. I thought just one is, but of course I don't dare print it. Even in quotation marks. As the new Puritanism sets in could we at least do some good social science research to figure out if folks actually INTEND to be offensive when they use certain "bad" words and if their listeners actually take offence when those words are used?
