alright so I traced the neopagan thing back to its source, and it looks like it ultimately came from Radio Free Europe, an interview with a Wagner commander. Obviously not everything that RFE publishes is false, but it’s not really my favorite source to rest my claims on. It seems like all other reporting on Utkin being a neopagan comes from there. If you want to take a look, here (it’s archived).
I think the neo-Nazi stuff rests on more solid ground though
