Does it require defeat in this world? It is worth remembering Charlemagne’s wars against Old Saxony. The Frisians and Saxons were conquered by the Franks and were forced to Christianity. Charlemagne had Irminsul cut down and committed a genocide against the Saxons. German military pressure on the Danevirke forced the conversion of the Danes.
Frankish military power and training as a warrior elite was the foundation of the Carolingian Empire. It is what made possible the conversion of northwestern Europe to Christianity and the spread of Latin culture among Germanic peoples who were never conquered by Rome. It is also what saved Western Europe from being overrun by Islam in Charles Martel’s time.
Suppose that Charlemagne had not conquered the Saxons but had instead operated on the “Christianity is for cucks” principle of modern day American conservatives. If the Saxons had not been converted to Christianity, would the Danes have converted? If the Danes hadn’t converted to Christianity, would the rest of Scandinavia? If the Saxons and Scandinavians had not converted to Christianity, would the Poles or the Balts had been converted later in the Northern Crusades? The Magyars who raided from the east and became the Hungarians?
If it had been up to American conservatives, Christianity in Europe would have been snuffed out by Muslims from al-Andalus and Sicily and by pagans from the north and by the Magyars from the east. England would have never existed because it would have submitted to Viking rule. This suicide cult for self-hating, deracinated, effeminate nice people isn’t the faith that established its dominance over Western Europe. It could have never defeated its rivals.
