O is not a half black dude. He is 1/4 black, 1/4 arab, 1/2 white.
Actually is is only 1/16th black, 7/16 Arab, and 1/2 white. But Arabs aren’t a race. They are a mixture of white and black, with most of them being more white than black.
If those proportions be true, then Hussein be 3/4 white, bro, cuz Arabs be white. So the bros in da hood, dey bes’ realize, dey done elected a honky.
