No, they don't. They are just the loudest voices. I've met a number of norse pagans who are good people. Also there are groups with names such as Facebook's "Nazis don't go to Valhalla".
If you feel Norse paganism speaks to you, or you like the 'Vikings and Runes' aesthetic, or you have that ancestry, or whatever, you don't need to let Nazis and reactionaries co-opt that or monopolize it. It isn't theirs. They don't get the victory of being the gatekeepers for any fucking thing.
Nazis get nothing except death.
