From King David to American Pentecostals, boisterous worshippers have always annoyed those who prefer their worship quiet and dignified. “Stop jumping up and down—we’re Episcopalians,” said a proverbial Protestant mother to her children. But the eminent sociologist Peter Berger approves:

There is ample biblical warrant for noisy worship. Perhaps King David was the prototypical Pentecostal when he sang and danced before the Ark of the Lord as it was brought to Jerusalem, along with his men, “making merry . . . with songs and lyres and harps and tambourines and castanets and cymbals . . . and with the sound of the horn.” Perhaps Mikhal, the daughter of Saul, who rebuked David for this unseemly behavior, was the prototypical guardian of properly polite etiquette. The mention of “joyful noise” is repeated in several Psalms, for example in Psalm 100: “Make a joyful noise to the Lord, all the lands! Serve the Lord with gladness! Come into his presence with singing.”

Two extraordinary events demonstrate something important about Israel’s most fervent adversaries. One was a speech given at something called The People’s Forum (funded generously by Goldman Sachs), which stated, “When the state of Israel is finally destroyed and erased from history, that will be the single most important blow we can give to destroying capitalism and imperialism.”

The suggestion that this tiny state is the linchpin of a global, centuries-old phenomenon like capitalism goes well beyond anything resembling rational criticism. Even if Israel were guilty of genocide, apartheid, and oppression—which of course it is not—it would not follow that its destruction would help end capitalism or imperialism.

The other was an anti-Israel protest that took place in front of New York City’s Memorial Sloan Kettering Cancer Center, deemed “complicit” in Israel’s evils. At organizers’ urging, participants shouted their slogans at kids in the cancer ward, who were watching from the windows. Given Hamas’s indifference toward the lives of Gazan children, such callousness toward non-Palestinian children from Hamas’s Western allies shouldn’t be surprising. The protest—like the abovementioned speech—deliberately conveyed the message that Israel is the ultimate evil and its destruction the ultimate good, cancer patients be damned.

The fact that Israel’s adversaries are almost comically perverse does not mean that they can be dismissed. If its allies fail to understand the obsessive and irrational hatred that it faces, they cannot effectively help it defend itself.
