Part of the success of liberal propaganda is getting liberals to performatively tell each other how propagandised they are as if it is totally normal, and for them to praise each other for it.
It's the same mindset as when workers boast about how hard they have to work, as if it's a good thing. Pride in being over worked, and admonishing other workers for not having it as hard as they do. Literally a culture of shaming other workers for not exploiting themselves hard enough for the bourgeoisie owners. They say it to each other with pride, not realising how much they're fucking themselves over.
