“Multiculturalism is an attempt by the elites to destroy the unity and cohesiveness of advanced white western societies so that they could better reduce them to serfdom and irrelevance while at the same time convincing the people in those societies to continue to work hard and turn over their money to them.”
If you’re going to say “advanced white western cultures” then you also should say “white elites”.
It is not merely “white elites” who are proponents of multiculturalism in the attempt to destroy western societies, though. It is all of them, because they all benefit from it.
