…Three years ago, a new anti-BDS group, calling themselves “Canary Mission,” entered the fray. They take their name from the recognition that Jews are the “canary in the coal mine,” the first to face irrational discrimination when societies enter into periods of increased bigotry and self-destruction. Their motto is, “If you’re racist, the world should know it.” Their members remain anonymous. They work at exposing campus anti-Semites, including students and professors, on the Left and on the Right. And they use the anti-Semites’ own words from their own social media posts to do it. They’ve created an online database full of anti-Semitic and anti-Israel tweets and Facebook rants, and dedicated pages listing personal and organizational ties to Hamas, the Muslim Brotherhood and other terrorist groups.
