Emerson Swift Mahon, born a Christian, left his native Grenada for Canada in 1912 in search of higher education and harboring a deeply-felt interest in Judaism. Two years later, he enlisted in the Canadian army to fight in World War I, and there met a Jewish chaplain named Herman Abramowitz. Eiran Harris writes:

Mahon persuaded Rabbi Abramowitz of his sincere desire to convert, and after a lengthy course of instruction in the intricacies of Judaism, an appropriate test of knowledge, and a religious ceremony, Rabbi Abramowitz signed the conversion certificate.

After the war Mahon settled in Winnipeg and graduated in 1929 with a science degree from the University of Manitoba. . . . Unfortunately, the Depression forced him to accept a job as a sleeping-car porter with the Canadian Pacific Railway. . . . In Winnipeg, Mahon joined Young Judaea, a Zionist youth organization, and quickly rose through the ranks. His work on the railway enabled him to organize chapters throughout Western Canada as well as to photograph every synagogue between Winnipeg and Vancouver.

Mahon also became proficient in Hebrew and Yiddish: “on the way to synagogue on Saturday mornings, it was quite common to observe Mahon urging his children, in Yiddish, to hurry along.”

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.
