Summary
Analysis
It is interesting, the narrator notes, that leftists want to join a Grand March against communism when communism has always been a leftist idea. Kitsch itself is not a political strategy; it is a strategy of images and metaphors, which makes it possible for a leftist to march against communism.
The narrator claims that communism is a leftist idea because it is supposed to be about equality and justice, although, in reality, it isn’t. Leftists are able to ignore this and participate in the Grand March anyway, and this willful ignorance is precisely why it is kitschy.
