Blood libel is a very old anti-Semitic myth that has stubbornly persisted for centuries, one of several conspiracy theories that have scapegoating the Jewish people for all of society’s ills at their core. The heart of the false claim is that Jews murder non-Jewish (or Gentile) children to use their blood for apocryphal religious rituals, during Passover and other prominent Jewish holidays.

Originating from a series of stereotypes about Jews amassed through the ages, blood libel is also intimately related to the global cabal conspiracy theory and was heavily used in Nazi ideology to justify the horrors of the Holocaust. Somewhat ironically, the Nazis claimed that the Jewish people were inherently violent and murderous — and used this baseless claim as justification of their own systematic program of violence and murder of over 6 million Jewish people in Germany during the 1930s and 40s.

The outlandish claims of blood libel have been thoroughly and repeatedly debunked by scholars, historians, anthropologists, psychologists, and an armada of dedicated truth-tellers — yet the stickiness of the myth persists, even after the consequences of this toxic belief system of antisemitism became apparent during World War II. Today, the blood libel myth has been given new life in the modern revision known as the QAnon conspiracy theory — a movement which contains elements of blood libel, global cabal theory, and a hodge podge of other fantastical and fanatical belief systems that have hooked gullible populations throughout history.

It’s important to remain skeptical of those who make these claims, and to ask who benefits from the deep virulent divisions and bitter partisanship created by the widespread belief in these toxic conspiracy theories.
