European aristocuckery towards Yehuborim goes way back, you could say it's their heritage to serve Yehuborim interests at this point. This only began to happen after they converted to xianity. You'll NEVER find a Pagan King serving Yehuborim.
Hitler called them out as well:
"In proportion as the powers of kings and princes increased, the Yehubor sidled up
to them. He begged for ‘charters’ and ‘privileges’ which those gentlemen, who
were generally in financial straits, gladly granted if they received adequate
payment in return. However high the price he has to pay, the Yehubor will succeed in
getting it back within a few years from operating the privilege he has acquired,
even with interest and compound interest. He is a real leech who clings to the
body of his unfortunate victims and cannot be removed; so that when the princes
found themselves in need once again they took the blood from his swollen veins
with their own hands.
This game was repeated unendingly. In the case of those who were called
‘German Princes’, the part they played was quite as contemptible as that played
by the Yehubor. They were a real scourge for their people. Their compeers may be
found in some of the government ministers of our time.
It was due to the German princes that the German nation could not succeed in
definitely freeing itself from the Yehuborim peril. Unfortunately the situation did not
change at a later period."
Most of the time, Yehuborim were kicked out of kingdoms because the kings became indebted to them and preferred to expel them rather than pay them back. This is what 1000+ years of worshipping a Yehubor as God turned European xians into, slaves for Yehuborim from the highest echelons to the lowest classes.
"but muh synagogue of sayten" some xian somewhere. They don't understand that Yehuborim kicked xians out of synagogues because they followed a distorted view of judaism. Yehuborim are completely fine with goys following it however. Some Yehuborim even support it.
The White xian is the Yehubor's best friend. Even if hypothetically they totally oppose the Yehuborim on a political, material level, they still worship a Yehubor, pray to Yehuborim angels, worship the Yehuborim "God" (which are the sefirots, so basically they're worshipping the Yehuborim collective soul), venerate a Yehuborim woman and so on. Even the natsoc xian is still fundamentally aiding the Yehuborim and submitting to them at a spiritual level, even if they don't realise it.
It's like saying you oppose a rival businessman but you still buy his products, promote his products, send him money, build him his shops with your money, but you still claim you "oppose" him.
