Correction on Fenrir lead to a ban
Someone asked about getting a better connection with Fenrir in the Norse Paganism sub and claimed fenrir is evil and burns the world, kills humanity and is locked away to protect humanity. I corrected this as in the eddas it is very clear that Fenrir is not the one who sets fire to the world, is never called a threat to humanity, and was locked away because of the prophecy of him swallowing Odin. This led to me being told I don't know the eddas and that I need an introduction to Norse mythology and that the gods being not completely good or evil is wrong and not how the old Norse viewed the gods. This spiraled with me constantly correcting the person as they were only going off the prose edda. I told them this is a bad methodology to learn the old stories and properly understand the material as it was written by snori and is a retelling of the source material and has exaggerated text. That you always cross reference with the primary source in this case with the poetic edda.
My question is am I missing something? How do you get through to people who ignore all the grey in the eddas and proclaim the gods are shining good and Loki is the devil. Are my corrections incorrect?
