The student government at Duke University has recently voted to fund a campus speech by a virulent critic of Israel. There is nothing wrong with criticizing any nation, but this speaker, Mohammed El-Kurd, says that Israel and Jewish settlers have “an unquenchable thirst for Palestinian blood . . .”. This is an obvious allusion to the ancient anti-Semitic “Blood Libel” that Jews use Christian children’s blood to bake Matzah’s.
