One of the reasons why the left hates European colonialism was because it was the only form of multiculturalism to work. You need a dominant tribe in order for it not to become a hellhole. Whenever you have a mixture of multiple tribes, there is going to be a dominant tribe. Whether that is simply the largest tribe or the most energetic tribe, there will be a dominant tribe. If you care for fairness and justice, you want the dominant tribe to be more just and more fair than the human average. The dominant tribe resolves disputes between the other tribes, and is sovereign, lest the environment grow chaotic and unjust. With colonialism you had a decently fair and just tribe (Whites) dominant over other tribes in various parts of the world. Many of these Whites lived with their subjects, but they exclusively held the sovereign political power. The only way to make multiculturalism work and not descended into some hellish dystopian warzone, is literal white supremacy.
