What they're describing (everyone being mixed-race, looking and thinking the same) is the globalists' dream.

It goes all the way back to Nimrod, who built the Tower of Babel as part of a plan to keep humanity from following God's command to split up and spread out over the Earth. Nimrod wanted everyone to live in the same massive tower-city and worship him.

God created different languages in order to foil this plan and cause the creation of separate nations spread out across the globe so that no one man or government could ever rule everyone again. The globalists, based on their plans and behaviors, seem to be followers of a Babylonian mystery religion based on Nimrod's ideology.

For all the lip-service they pay to diversity, their ultimate end goal is the end of diversity; a boring, homogenized version of humanity who all look, act, and think the same.

From the ancient historian Josephus:

"Now the plain in which they first dwelt was called Shinar. God also commanded them to send colonies abroad, for the thorough peopling of the earth, that they might not raise seditions among themselves, but might cultivate a great part of the earth, and enjoy its fruits after a plentiful manner. But they were so ill instructed that they did not obey God; for which reason they fell into calamities, and were made sensible, by experience, of what sin they had been guilty: for when they flourished with a numerous youth, God admonished them again to send out colonies; but they, imagining the prosperity they enjoyed was not derived from the favor of God, but supposing that their own power was the proper cause of the plentiful condition they were in, did not obey him. Nay, they added to this their disobedience to the Divine will, the suspicion that they were therefore ordered to send out separate colonies, that, being divided asunder, they might the more easily be Oppressed.

Now it was Nimrod who excited them to such an affront and contempt of God. He was the grandson of Ham, the son of Noah, a bold man, and of great strength of hand. He persuaded them not to ascribe it to God, as if it was through his means they were happy, but to believe that it was their own courage which procured that happiness. He also gradually changed the government into tyranny, seeing no other way of turning men from the fear of God, but to bring them into a constant dependence on his power. He also said he would be revenged on God, if he should have a mind to drown the world again; for that he would build a tower too high for the waters to be able to reach! and that he would avenge himself on God for destroying their forefathers!

Now the multitude were very ready to follow the determination of Nimrod, and to esteem it a piece of cowardice to submit to God; and they built a tower, neither sparing any pains, nor being in any degree negligent about the work: and, by reason of the multitude of hands employed in it, it grew very high, sooner than any one could expect; but the thickness of it was so great, and it was so strongly built, that thereby its great height seemed, upon the view, to be less than it really was. It was built of burnt brick, cemented together with mortar, made of bitumen, that it might not be liable to admit water. When God saw that they acted so madly, he did not resolve to destroy them utterly, since they were not grown wiser by the destruction of the former sinners; but he caused a tumult among them, by producing in them divers languages, and causing that, through the multitude of those languages, they should not be able to understand one another. The place wherein they built the tower is now called Babylon, because of the confusion of that language which they readily understood before; for the Hebrews mean by the word Babel, confusion."
