Recently watched on TV very funny and clever comedian from South Africa. "The African American", His show is called. He says there that when a person is half black and half white, he still black.
Children of interracial marriages, despite having half or more white blood, go into the black culture. With few exceptions, of course.
The same thing happened with our president. Being half white and completely not familiar with his black father, he eventually chose to be a black man and not white. This is his free and awareness choice.
Where possible, it supports black against white, which is absolutely not allowed to the president of a country like the U.S., which was created by white settlers from Europe.
What a warm feeling it can cause to the white population of the country, unless they are suicidal?
