There is a palace that erases the ugly symbols that write on its walls. It was taken over by the cameras.
The moment someone draws such a symbol, the building blushes with rage and makes it disappear. It’s ok to write phrases like “I love you” but also “horned” but not, for example, the swastika.
We think of all those idiots nostalgic of dark times who have fun smearing the streets with these symbols.
Some small parts of the building were subtracted to analyze them in the laboratory. Some pieces have been used to create new anti-swastika palaces.
By dint of taking parts of the “fabric of the building”, however, this is getting sick until it loses its erasing power.
