Yeah. If it's not clear that it's a retooling of cultural bolshevism from his speeches in general, watch his prager u video on it and its pretty clear.

I cant really comment in gramsci, never even listened to a podcast about him, let alone read his writing, but I think it's something along the lines of what the cultural revolution was trying to deal with in regards to capitalism/liberalism shaping the ideological super structure of society.
