I drove past the local immigration welcome-wagon center last night. There was a whole crowd of Africans "fresh off the boat" milling around outside.
Until about 5 years or so ago, there were very few black faces seen around here. Then the UN directed the US to start taking in black Africans. The US obeyed their marching orders. Now, places in America that previously were almost totally white in population now have sizable and growing numbers of black Africans. Diversifying can be interesting, indeed.
The impact of growing numbers of black Africans on American society will not be interesting.
