It’s always the patriarchal conquerors like the Ancient Romans or the Ancient Greeks that they idolize and never the people like, say, the Picts or the Celts or the Gaul that rebelled against the brutal Roman empire. It’s never the Scottish or the Irish heroes who fought back against the British Empire that followed in Rome’s footsteps. None of them probably even know who Boudica is.
Ironically, a lot of the stuff you could call “white culture” was burnt at the stake, banned, brutalized, and literally demonized by the Empires that chuds think are so civilized. A lot of pagan culture was lost to time, or warped by Roman ‘scholars’ for propaganda purposes. If they truly cared about their ‘culture’, then "Muh Christian trad wife’ would be seen as killing the identity of pagan women, rather than an aspiration.
For a revival of nature worship, we would first have to be sure that pre-christian and pre-roman societies did actually practice anything of the sort, which we are not.
On top of that, I’m not sure that a religious movement is necessary or desirable for nature advocacy or preservation.
american natives were tremendously successful in reshaping the landscape and environment to suit their needs and hold nature in deep esteem. land as kin is totally sufficient. a peer relationship, in other words.
We do know it occurred in Indo-European societies, but it was not born of love of nature but close dependence on it.
Shinto religion is an example of humans still doing a form of nature worship in my mind. Assigning spirits to everything and worshipping those spirits and the “balance” of them is in its way the worship of a natural system. It’s very very against the destruction of ecosystems and nature because it’s incredibly harmful to the spirits, so while nature might not itself be the thing being worshipped by Shintoism the spirits created by nature require the protection of nature in order to exist. It’s somewhat close.
Ok so it’s not based in europe but does it matter? Humans can worship nature elsewhere so you could essentially create such a religion for the european context instead.
