It is much easier to describe how anti-Semitism works than what works against it.
Anti-Semitism is a hatred. At heart, it is a conspiracy theory positing that Jews conspire to harm non-Jews. Like most conspiracy theories, it provides easy answers to difficult problems.
Of course, the world’s problems are rarely simple. Neither is anti-Semitism, but we sometimes choose to look at it as if it is, perhaps for reasons similar to why anti-Semites seek easy answers too.
The first of the usual bromides is Holocaust education. Surely it’s important that people know about the Holocaust. But how is teaching about the Wannsee Conference and Kristallnacht going to change people whose anti-Semitism is connected to seeing Jews with guns lording over their Muslim brethren in the West Bank? Or those, already well-educated in Holocaust terminology, who gleefully use terms like “ethnic cleansing” and “genocide” to describe Israeli actions that may be discriminatory, but are certainly not Nazi-like?
