Here in the US it's usually fruitcake leftists that seriously observe pre-Christian holidays, but in Europe there has been a growing movement on the right of people observing Pagan festivals. In light of the attacks on European culture by both immigrants and governments, Europeans are reaching into the murky pre-Christian past seeking fundamentally European culture. I've talked to Europeans who view Christianity as "the first Middle Eastern attack" on European identity. So they search into the ancient Germanic murk for undeniably European-originated faith. I've heard some crazy stuff about how the old gods went to sleep when Europeans turned its back on them and that the spirit of Europa will rise up to smite the invaders if Europeans will return to their Pagan roots.
Just goes to show how many tools Satan has at his disposal.
And, of course, Wagner, that evil German of great genius, used some of those myths in his operas and eventually influenced evil, pagan Nazism.
