i think one of the aspects of fascism that really freaks out liberals is that fascism is the return of the policies they (casually or explicitly) support overseas to their homes and applied to them and their neighbors. i was reading that post-colonial analysis excerpt about how hitler did to the core what “heroic” churchill and his predecessors had been doing to india and other peoples/nations for decades. libs avoid any material analysis of the core/periphery or fascism because the connections make it obvious libs have no trouble enjoying the fruits of evil done elsewhere to secure markets, but bringing those same methods of repression and control home is the unspeakably evil act of a madman.
the idea that their poorly-interrogated political project creates and necessitates the very monster they fear is too much to grapple with for some.
