the problem with globalized politically correct multiculturalism is that it always seems nice and cool in the ads and holywood movies, but in reality it's a whole lot different story. People tend to stick to their own kind based on skin color essentially and it still remains to be seen how the very few interracial relationships that started during the last trend will end for both men and women, and their kids if they happen to breed.
In the end you have more and more single dysfunctionnal parents, families, and kids with no roots , no education and huge identity issues who in return will contribute to pollute society and fail to be socially functionnal.
