There's a strange uniformity in the vocabulary European soccer fans use to hate black people. The same primate insults get hurled. Although they've gotten better over time, the English and Italians developed the tradition of making ape noises when black players touched the ball. The Poles toss bananas on the field. This consistency owes nothing to television, which rarely shows these finer points of fan behavior. Nor are these insults considered polite to discuss in public. This trope has simply become a continent-wide folk tradition, transmitted via the stadium, from fan to fan, from father to son.
