It probably shows my age Maoism was a "thing" when I was at University. Its feature was that it was a species of Marxism that was/is particularly concerned with "culture" as well as economics. In its most extreme form its what drove the "killing fields" in Cambodia. Basically that everything of the old culture (false ideological consciousness) had to be obliterated. Hence the "Cultural Revolution" in China and things like the mass "re-education" of the Uighurs currently. Of course Leninists had much the same idea however by WW2 Stalin had realized that few would fight for an "ism" and so revived notions of motherhood and patriotism.
