The swastika is a potent symbol, massive swastikas made up from chairs in the classroom more so. So we assembled one. It worked, but the culprits hadn't thought about quite how pissed off the Jews might be by this - certainly no-one had considered that they might complain to the head of year. The school, entirely understandably given that about 30% of its pupils were Jewish, took a deeply dim view of neo-Nazism, which taught us an important lesson. Extreme right-wing politics, fascism, and genocide are bad, okay kids?
