I'm definitely still internalizing his argument, but I think Roderic's broader point is that the imperial proletariat (assuming you're in the west like myself, if not, then I apologize for projecting)

instinctively and correctly understand that they benefit as a class (as a global bourgeois proletariat) from the exploitation enabled by their military and their propaganda (in Gramscian: organs of coercion and consent).

So it's not that ignorance doesn't play a role, I also was ignorant of a lot of history until just a few years ago, but it's more that we have instinctively internalized that openly fighting back against these propaganda narratives would not materially benefit us, even if we haven't made that overtly clear to ourselves. (Now in my own words:) It's much much easier for us to simply go with the imperial flow, because, even if we're poor as shit by first-world standards, we still have it better than the third-world, global south proletariat (and we do so because we benefit from their exploitation!). It's definitely an uncomfortable indictment, but at least brings the power of propaganda down to a less mystical level.
Of course, there absolutely are people who revel in and relish the propaganda, just look at
