The new evidence points to a population replacement having occurred to a greater extent than academics had anticipated. That is alway a topic that involves nationalist rhetoric because people would rather believe they had been always there, not that they descend from the invaders, or even the next wave of maigrants.

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.
