This article is about how the US and Canada are shifting the blame for the boarding schools that killed thousands of natives for generations and the forced assimilation of those people... but yes, be upset that the title alludes to DNA I guess.
It's real easy to find the author's use of the term "DNA" in the title upsetting, when you're not in the hundreds of indigenous groups who've been forced into generations of oppression at the hands of Anglos. It's a provocative title, it's meant to catch your eye. Now actually read the article, and understand that it's pulling attention to the treatment of indigenous people by Anglo governments. Treatment that Anglo governments are currently trying to deny while claiming the boarding schools for the Uyghur are the same thing.
Really think the title of the article is a problem? tell that to the Beothuk people of New Foundland, who were wiped out by settlers - it was a genocide.
Tell it to the Koroa of Mississippi, who died from European diseases and assimilated into the stronger nearby tribes to escape the English settlers.
Tell it to the Westo of the South East, who were killed off by war with the Carolinian settlers.
Or to any of the various tribes history forgot, because the murderous Anglos didn't deem it important enough to catalogue them. Tell it to the millions of Africans who were enslaved by the Anglos in West Africa and sailed into the Americas to act as a labour force. Tell it to the Palestinians who are actively being killed off by the Anglo Backed Israeli government.
