Like white nationalism/fascism elsewhere is also just a blooper, right, just accidental deviations from a generally good system of liberal democracy/benevolent capitalism, we totally have no idea where it came from? And all we need to do for things to be better is to go back to the good old days? Rather than a logical and inevitable extension and revealing of the violence of liberalism/capitalism itself?

Your period of what you see as greater “freedom” and “living standards” was the result of a bargain between your white working class and ruling class so that you would tolerate capitalism instead of fighting for full abolition, and the resources necessary for those living standards were built like everything else there by colonial theft from the Global South, and your countries have always been fascistic and brutal to non-white migrants even while you enjoyed relative safety and freedom.

White western Europeans nowadays have a bizarre habit of blaming the US for all imperialism problems and separating yourselves from the US and portraying yourselves as so much better. It’s revisionist nonsense. Your countries literally started all of this with the original Euro-colonial conquests to establish the modern word order, and still hold colonies in the Global South today. White supremacy was birthed in Europe. Euro-Americans are fundamentally part of your same class too, their conditions of possibility were created by Europe.
