Here’s a shocking story. A student, active in white racial politics, gets cross because he sees a black student filming him. He knocks the smartphone out of the black student’s hand and then posts on Facebook: “I wish I’d actually not been a good law abiding citizen & whupped the black sass out of the bastard”.

The same student had earlier boasted of reducing a waitress to “black tears” after refusing to tip her. Yet, curiously, he has a following in the media and even in politics.
