Ah, the third rail of our community.
Let me settle this in the first paragraph. I do not see why I would actively try to stop someone from practicing the Norse religion when they are clearly not of the blood, who I am to say they were not called? But personally, I think that is DUMB. This question is almost silly to me. Of course indigenous religions should be folkish. They are by definition.
In the same breath I think it would be foolish to claim one’s religion was somehow better or closer to the truth than someone else’s religion. We are all in the same boat, trying to make sense of the vast universe and our role in it. By the same token, it is only natural to try to do this in the fashion that your own people have for thousands of years. To each group may have been revealed different truths? Let him with the true answers cast the first doubt upon someone else’s beliefs, not me.
I am most comfortable knowing I try to follow the path of the people before me who are literally the reason I am alive. It is human nature to want to be surrounded by people who share traits, customs, and beliefs with you. By the same token, the Vikings were famous for travel and even wanting to meet new peoples and establish trade. Early Germanic groups were almost nomadic in their European wanderings for a homeland.
Maybe a quick anecdote?
Why is the Christian hell hot? Because Christianity is a desert religion from a desert people. Any people who, when imaging their own hell, would naturally exaggerate whatever condition in their everyday lives they hated or even feared. Ask a guy in the desert what hell is like. Lake of Fire, no water to slack the thirst, burning of sinners all around you. The heat, my god the heat. Makes perfect sense.
What would a Norseman think hell was if he had one? Bitter cold, unending hellish cold. Howling wind and blinding snow. You can never get warm for all eternity.
The Norse did not have much of a consequence to living badly so much as a reward for living correctly. But you can see how one view of hell would have been natural to us as a people and one was foisted on us from a conquering religion not native to our lands and lives.
If I were a Greek Helot I would dig on what Jesus had to say, but I come from a different stock and a ‘thou shall not‘ morality does not appeal to me.
To be folkish is to be true to our ancestors. Think just how much has to happen in just the right way to bring you where you are?
The other argument that I find stupid is to argue that Vikings were decidedly not racist and therefore heathens should not be folkish. Not really a persuasive fact either way. Their world was far from ours and not one in which anybody contemplated the same notions of multiculturalism and all that decision entails. Folkishness and racism should be treated as two separate things instead of being lumped into one all or nothing paradigm.
