Yep, figured that someone would call that pile of crap 'satire' and then throw the snowflake PC flag on the observation.
Since that's NOT the dialect of any American Indian I know of, in or out of my family, I'm going to also call your equation absolutely bull too. It was entirely made up for fictional portrayals in books and movies to make Indians appear uncivilized.
But bless your heart anyway.
Which is more offensive a liar pretending to be an American Indian for advancement and economic opportunities or using fake Indian jargon to mock said liar? True that no American Indians talk like that but the author is mocking a fake American Indian, Elizabeth Warren.
Try to take yourself out of it and look at it from the perspective that this is directed not at you or any real American Indian but at someone pretending to be one. Like actors pretended to be when they would say those cheesy lines in old movies.
Looking for a reason to be offended is a miserable way to go through life, look at liberals.
