As much of the formal leadership of the Black Lives Matter movement seems eager to embrace the anti-Israel cause as its own, and, just last week, as two scandals erupted on social media involving black celebrities disseminating anti-Semitic canards and slogans, black-Jewish relations don’t seem to be at their best. Yet Saul Singer reminds us that these troubling incidents need not be taken as representative. He draws our attention to the sympathy for Jews and the Jewish state of two great leaders of the civil-rights movement: Rosa Parks and Bayard Rustin—the latter of whom was also a regular contributor to Commentary magazine:

Though Rosa Parks’s heroism on that Montgomery bus has become the stuff of legend, not as well known is her strong support of Israel as a Jewish state and determined opposition to anti-Israel boycotts. In 1975, she joined a list of over 200 black leaders organized as the Black Americans to Support Israel Committee (BASIC) in signing an open declaration of admiration and respect for Israel.

BASIC was born just after the Arab League recognized the PLO as the “sole legitimate representative of the Palestinian people” and after the United Nations passed its shameful Resolution 3379 equating Zionism with racism. The civil-rights leader Bayard Rustin responded in a column that “Zionism is not racism, but the legitimate expression of the Jewish people’s self-determination. . . . From our 400-year experience with slavery, segregation, and discrimination we know that Zionism is not racism.”

Throughout his life, Rustin remained a champion of Israel who manifested ultimate faith in Israel’s democracy. He expressed great antipathy for Arab governments and for the PLO, which, he said, used Israel as a facile excuse to divert the attention of the Arab masses away from their own treachery and political failures: “Marx once said that religion is the opiate of the masses. In the Middle East, Israel is the opiate of the Arabs.”

Rustin characterized anti-Semitism as “history’s oldest and most shameful witch hunt,” and he was particularly disturbed by black anti-Semitism, which he publicly acknowledged: “We cannot sweep it under the rug; . . . it is here, it is dangerous, it must be rooted out.” Such statements earned him the enmity of many in the “Black Power” movement, which he bitterly criticized for its anti-Semitism and Israel hatred. He faced vicious accusations from the radical left, who called him an “Uncle Tom” who had been “bought out by Jewish money.”

Rustin [later] became a close friend of the Israel prime minister Golda Meir, who once made him her famous chicken soup to help him recover from a bad cold.

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.
