What is the difference between "people of color" and "colored people"? Some White people think that non-Whites are going to save them from other Whites, when most non-Whites see them as ass-licking traitors. The non-Whites would never go against their own. You will see Hispanics stand up for their culture and people and not sell out. They do not really believe in multiculturalism, except as a means of getting something.
Take China. If you are not Chinese your are nobody and even if you are and don't follow the party line you are less than nobody. The reason China will rule the world is two fold. One is they believe in themselves, the other is they know once Europe and the USA fall any real threat will be gone and because the Whites are too stupid to see they are committing cultural suicide. Once the Whites are in disarray the non-Whites will eat them alive and be more than willing to live under Chinese rule.
Trump knows this and yes he is a nationalist, but he won't win because there is no stopping the evil of progressives to distroy the USA and the power of China is too great. The USA will become a waste land eventually populated by Chinese people.
