That moment when you realize that you can't distinguish "Viking" from "Scandinavian"
Just messing :) But seriously, that'd be like an English person saying that they're a knight, or a Japanese person saying they're a Samurai. Viking refers only to a military class (A broad one, but a military class nonetheless).
I'm crying on the inside at all of the people calling themselves vikings. Are all English people knights? Are all Greeks hoplites? Are all Japanese people Samurai? No, you wouldn't call a Norwegian knight a viking, nor a modern Scandinavian a viking.
Here's some knowledge for you: https://youtu.be/DwMtqUIQwU8. I hope I've contributed to ending this misunderstanding.
You do realize that we Scandinavians refer to ourselves as Vikings in a joking way, right? We're not being serious. But just like there are still knights nowadays and still Samurai there are some Vikings in Scandinavia nowadays. People who do stuff like sail long ships, hunt and fish and farm for food, practice archery and sword fighting, do woodcarving, wear cool Viking clothes and Jewelry, and practice the Åsatru religion, myself being one of them. It's actually a genuine way of life that is growing in popularity here in Norway, I heard that there is even a school in Norway that offers a Viking course that teaches people all the skills I mentioned above. And yes, I know if you want to be skeptical you can say that they are not actually the exact same as Vikings from the middle ages, but Samurais nowadays aren't blood thirsty honor maniacs, and most knights aren't remotely similar to the middle ages type, yet still they have the right to call themselves that, and it's the same with us.
I would still argue against your way of life actually being "Viking", because while Knights and Samurai eventually became an attainable social symbol which endured to the modern day, Viking remained a military term. Not held in the same light as military positions today, and coming with social benefits, but still not a social class. Following their religion, sailing ships, hunting, farming, or even using their weaponry and clothes do not denote a military position; in fact, I would contend that it is even insulting to their memory, and the battles they fought.
Also, because of the several hundred years between now and the end of the Viking age, it would be more appropriate to refer to people who follow the way of life of the early medieval Scandinavians as just that: people following the lifestyle of early medieval Scandinavia.
