Its an extreme form of white privilege and domination in that whites do strongly fetishize the suicide of their own white culture, but other cultures feel no need to suicide their culture just because whites have a weird desire, and telling them they're going to have to eliminate their traditional family life or bulldoze their mosques or forget their traditions and holidays and histories to fit some kind of white ideal of zen like annihilation of the self is pretty racist and is likely not to work so well.

In disagreement with grand OPs daydream of a multicultural future utopia, the multicultural area of the future probably looks a lot more like multicultural areas of the present and recent past, the burbs of Paris burning, genocide in Africa and the middle east, raping and violence by refugees in Europe. The multicultural world of the future will look a lot like Syria, lets say, but angrier more violent and less functional, and it'll be everywhere not just "over there". Except for the rich people in their gated communities profiting off all of it.
