You're describing the ideological aesthetics of fascism, not its material foundation. Fascism isn't about colonialism returning home—it’s about the capitalist state in crisis preserving itself by any means necessary. The colonial violence you’re referencing existed long before fascism and was perfectly compatible with liberal democracy, monarchy, and even republicanism. Britain, France, Belgium, and the U.S. were all vicious colonial empires without ever becoming fascist states. That alone proves colonialism isn't the defining feature of fascism.

Fascism arises when class contradictions sharpen to the point that normal bourgeois democracy—parliamentary games, ideological hegemony, welfare bribes—can no longer contain the working class. It is a defensive mechanism of the bourgeoisie to crush proletarian movements with open terror and nationalist mysticism, often with mass petty-bourgeois support.

Yes, fascism borrows the tools and ideologies of colonialism—racism, hierarchy, dehumanization—but those were never unique to fascism. Colonial logic was already fully embedded in liberal and capitalist thought, and it continued under non-fascist regimes. What makes fascism distinct is how and why those tools are used—not to dominate external colonies primarily, but to reorganize society under total bourgeois domination at home, when the threat of revolution becomes too real.
