Modern paganism went through a revival during the early 2000s. Are you sure you're not just seeing someone's religion?

And its not the first time, either. There's been several revivals of the beliefs and culture over the years - for example, we didn't even have the word 'viking' in English until the 18th Century.

No, that's not specifying the Viking job, just old nordic culture. I don't think that anyone wearing a cross is pretending to be a crusader.

There was that one Indian guy who hit the gym, bleached his skin and hair and now does a pretty credible Viking impression.
