:I totally agree and note that it's very important to do that, I don't have time; and it gets complicated though yes, it's largely seen now as derisive and always was.  Still, you'll find in the old Handbook of American Indians, I think it is, a chapter on the "Siwash Indians", meaning the Salish of Puget Sound and others.....many BC placenames have been changed that had this, though several remain.  Like Gweilo and Chinaman and others, a word with a history and it deserves a lot more than a terse disambiguation page for sure.
