Ever since white nationalists used Viking metaphors, the system has been in over-drive to deconstruct the Vikings. As I covered in an Alor.org paper in December 2020 (use the wonderful Alor.org search engine) we have seen things like transgender Vikings, Muslim Vikings, and anything to legitimated mass migration into Scandinavia, as their part of the Great Replacement.
Now comes the claim that being a Viking was a job description, not a matter of being a Norseman, or heredity. The genetic study of Viking-style graves has allegedly revealed that there were Vikings in the Orkney islands, Estonia, and other places, who had no Scandinavian DNA. There was even found a Saami skeleton. However, it is admitted that various people were so impressed by the Scandinavian Vikings that they took up Viking ways, and this is what is found in the graves. It is even possible that Vikings, as basically pirates, may have taken in various non-Nordic individuals who impressed them, just like organised crime gangs do today, while maintaining an elite ethno-racial core. So what? It does not show that Vikings were all Africans, or Muslims, which I suppose is that the woke want.
