and if people think that NDN is offensive you can tell them “it stands for Native Demographic Northamerican—and, besides, only us NDNs can use it, paleface.”(*)
just the same way that, as a person all four of whose grandparents emigrated from Italy to the USA as children, i can tell jokes about wops (of which i know a few that, really, don’t work about any other ethnic group) but i’m entitled to get offended if anyone else does. which drags the topic back to Italian culture and hence pignoli nuts. My wife is Irish, but she has shown her good taste by adopting pignolis, wine biscuits, and ricotta as some of her favorite foods—and, of course, by marrying me.<grin>
(*) or “Native Demographic NewWorldIslander”, so as not to disrespect any people of native South American ethnic heritage—say, contemprary with the Clovis culture.
