Here in germany there are tons of self-identified pagans, especially in right-wing circles. I think this is mostly a consequence of anti-christian policies of the DDR. People in eastern germany have no connection to religion anymore.
My strong impression is that in all cases it is not much more then larping. Empty imitation of rituals. And how could it be anything else? There is no continued tradition, no one grows up as a pagan. We don't know what these beliefs even meant to people 1500 years ago. Also all past religions were deeply connected to the world people were living in. Crazy to think it makes you a pagan to live a modern life with 5-9 job and smartphone because you now make a big bonfire from time to time.
I think in that case they are attempting to reconstruct paganism and therefore create new traditions.
