I enjoyed this argument for the author’s deep scholarship of the issue, as well as the time they put into their argument.
One key point in their argument is that a clarification of terms is necessary.
Universalist can mean a lot of things. The key understanding that most people have, is that Universalist opens Heathenry to all people, regardless of their ancestral background, while Folkish Heathenry believes that only people with European or Northern European ancestry should follow the Norse Gods.
Many people assume that Universalist Heathenry has more syncretism or less reconstructionism than other forms of Heathenry, when that is not necessarily the case.
So read this argument and enjoy.
