Can you point to any nationalist rhetoric from people working in the field? Among the handful of current scholars in Poland, Ukraine, and Russia -- i.e. the countries relevant to the article -- I doubt anyone feels anxiety about possibly having Goths among their ancestors. That happened so long ago (nearly two millennia ago), and there are obviously more recent conflicts that weigh more heavily on people's minds and national consciousness.

Well, I was thinking of Kyiv Rus, which appeared almost a thousand years later and were arguably Slavic people with a Scandinavian elite... but if you read the history in different languages around the region they once inhabited, you'll get quite a different picture. I don't know if there's something similar about the Goths, but I am just saying that the academy apparent preference for the Goths having been just a moving culture for the most part, with little population displacement, seems quite biased towards the very common "our people were here for eons" narrative, from the outside.
