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.
Also the idea of Christianity being colonial in its spread in Europe isn't really accurate. The English weren't conquered and forced to give up the old gods they gave them up willingly. Christianity was even a rallying cultural symbol against the slavery and conquest of the norsemen. The Romans at the time of their conversion were even the imperial power
I've even seen someone claim that the reason some norse folklore portrays nature as harsh and dangerous is Christian influence demonising their old gods and not the fact that of course they think nature is harsh they lived in Scandanavia. Nor is Christianity more anti-nature than paganism. Christianity and Abrahamic faiths do include explict language on stewardship of nature and the Romans under their old gods quite happily made Carthage into a desert and would as a tactic of occupation punish revolt by for example burning the heather and salting the earth
