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.
This is certainly true of the reactionaries of today although strangely Victorian Britain did sometimes use Boudica, and celtic resistance to the Roman occupation in general, as something of a propaganda tool against rival European powers which is pretty confusing. Guess it's a bit like how right wing Italians will try and invoke Giuseppe Garibaldi even though he was involved in the First International.
The first international what?
The International Workingmen's Association, the first large international organisation of socialists and proto-socialists.
