Racism in the United States is astonishing. As a non-American, until Obama’s time, I used to think that, there was just some institutional racism left over from past decades and a few extremists in the South—but not much else. After Obama, it’s incredible how most white people have become extremely right-wing extremists, all because of a single president of mixed descent. Now, the problem seems enormous, and a solution doesn’t appear to be anywhere in sight.
