That is why I chose that particular country, and not any other African Country. But again, you can garner the same results that occurred by substituting values other than location, and black and white. Of course there is racism in America, and of course the fact that the ruling class, save it's current political leader, marginalizes black people. You don''t go from rolling children's heads down the side of a temple, to slavery, to marginal equality, to equality, in a day, or even thousands of them apparently. I still think it is less of a direct issue with color and more a direct issue with the psychology of the person, or people.
The point is that this is not one isolated issue. This keeps happening because there is a cultural sickness in America that demonizes blackness. This has an important socio-historic context, which is what the article is about.
