Unfortunately a lot of the pagan and related spiritual movements are being coopted by white supremecists. I find this stuff fairly attractive as someone with Scandinavian heritage, but it seems like I've been overtaken in the space by racists and fascists.
The BBC piece explicitly mentions this - with almost no ties to politics and an open door policy for all people - but I am aware that other groups are not as open. This cannot, however, be generalized.
Some folks do hold the believe that people with a different heritage should follow their own culture's roots, which often results in a very similar line of thoughts an beliefs, yet differs in customs, names, rituals ..., but ultimately leads to the same guiding principles. I personally don't agree, given our modern societies, but it can be regarded as a valid thought that is not driven by racism, but merely by the guiding idea of remembering the old ways, regardless of where those might be rooted.
Jesse Byock's translation of Snorri's Edda touches on the historical aspect of this in the prologue as well as his annotations. It's a great read if you are interested.
