Imperialist Multiculturalism: Erasing Sweden's History
Viking artifacts are being melted down to scrap metal. Sweden is destroying historical objects from the iron age to save money. But also, there is political bias permeating the entire world of museums and cultural heritage. Main figures regularly expouse moral panic about racism, and find Swedishness to be "problematic". One of them even converted to Islam to become less Swedish.
Old things can provide a lot of value for the future. A tablet was discovered a while back which ended up rewriting the history of math, for example. This could apply to other scenarios as well, and this shows why multiculturalism isn't just a harmless idea. It has the same effect on culture as authoritarian dictatorships throughout history.
