This is an asinine thread.
Culture isn't static and should not be.
If anything, the bourgeois ideologues have only not gone far enough, if even possible for said bourgeoise, in forging the new culture.
In addition to creating new proletarian culture, the Soviets rewrote fairy tales to remove feudal and patriarchal elements, sometimes without even being subtle about it. For example the princes and princesses are replaced with Soviet administrators and humble peasants. And That doesn't even go to Soviet films, for example, 20,000 Leagues, which has even stronger, the original having a little already, antiimperialism themes. Link rel, the famed Chinese writer, took old tales and told them in service of revolution. There are many films, to give more examples, that have been appropriated, too, by LGBTQ people to be used for the struggles. And obviously, there's the retelling of Exodus by the enslaved Africans to serve their journey towards their liberation.https://www.marxists.org/archive/lu-xun/index.htm
If there is ever a revolution, this only will be developed even more, because all culture must change in tandem with their society's base.
