The first duty of a Viking household was to show hospitality to any and all who came to their door. That white nationalists try to use the Old Norse religion to justify hatred against Muslims, immigrants, and refugees is an affront to the pagan heritage they claim to be protecting.
Trying to understand the Vikings takes some patience and careful research. They built homes of wood and turf, and their clothes were mostly wool and linen, so much of the physical evidence of their travels and lifestyle has been ravaged by natural processes. Viking societies depended heavily on oral communication, and many of the texts we have today were written down a century or more after the Viking Age. Determining how the information may have changed over that time is tricky business, and we can only guess how many stories were completely lost over the years. One story that has survived is the Christianization of Iceland. But did the Icelanders turn to Christianity out of fear of volcanic eruptions, as some researchers have suggested?
