Some time last year I was reading Kleinzeit, a surreal metaphysical novel by Russell Hoban. At some point the character is taking the Underground across London: On a film poster a famous prime minister, shown as a youthful army officer, pistol in hand, glared about him, said in handwriting, I must kill someone, even British workers will do. KILL WOG SHIT, answered the wall. The novel was written in 1974. Thinking back, I could vaguely remember that yes, racism like that used to be a thing.
