Did marx at one point write about "take over and make mockeries of entertainment"?
It's becoming such a common thing it's on par with "attack cops" in the commie play book. What's the ideological driver of taking over and destroying entertainment franchises?
Destabilization of Culture is the phenomenon you're talking about.
The ideologue you're looking for isn't Marx. It's the Marxists who looked at the industrial societies resisting the revolution that came to Russia and China and asked: why hasn't this worked in the West? They railed against "Stabilization." They were upset at the prosperity which made the proles happy with the capitalist system. These neo-Marxists chose to erode the culture itself because they couldn't oppose the material wealth; they did this by focusing on intrinsic differences. They aimed to create a new class of "oppression" to create sett of proles who could never be happy once they were taught that they were oppressed.
Then they conducted a long march through academia to ensure that they'd be the teachers. They seized the means of cultural reproduction, instead of the factories. The creative arts followed, resulting in the destruction & subversion of modern media.
Welcome to our intersectional future: miserable people subverting and ruining our culture because of the way they were born.
You think that it comes under Demoralisation/Destabilisation of active measures?
Basically. It's done by neo-marxists focused on culture rather than overt communists, so it's different. They've cloaked themselves in Post-Modernism to play a longer game, but the ideological goal is still the revolution, with the promise of utopia to follow. All present culture is on the chopping block because it's in the way of a "greater good" so great that everything blocking it can be sacrificed and/or destroyed.
It's zealotry, but the religion is secular.
Through it, all measures against the oppressors are justifiable. ("No bad tactics, only bad targets")
