According to me, anti-Semitism as an attitude is not the worst of sins, but it is a dangerous one. It is the first step in an exclusion mechanism that starts with social avoidance and in its extreme form leads to death and destruction. That is why it should be dealt with thoroughly in public debate. . . . When a leader of an organization is caught being anti-Semitic the organization must make it clear that this was not done on its account. This is even more true for a psychoanalytic organization. Only then can things return to normal.
