A vintage comic book-style illustration that shows Superman lecturing a group of students on the values of tolerance has circulated widely on social media. “And remember, boys and girls, your school—like our country—is made up of Americans of many different races, religions and national origins,” Superman says with a wag of his finger, “So… If YOU hear anybody talk against a schoolmate or anyone else because of his religion, race or national origin—don’t wait: tell him THAT KIND OF TALK IS UN-AMERICAN. Help keep your school All American!”

The illustration is authentic. It was drawn by Superman comic book artist Wayne Boring around 1949, and it was stamped on a protective schoolbook cover (one of which recently sold at auction for $805) and a poster. But the comic is more than a quaint piece of Americana; it’s a relic from a largely forgotten nationwide tolerance movement that swept the country for more than a decade. Powerful people in government also suspected Superman’s brand of patriotism was ... anti-American propaganda.

THE TOLERANCE MOVEMENT

During the 1940s, America basically underwent a nationwide sensitivity training program. Zoe Burkholder, a historian of education, writes in the Harvard Educational Review that a “forced tolerance” movement had begun frothing a decade earlier as educators feared that scientific racism—the pseudoscientific “Master Race” theories brewing in Germany—could waft overseas.

Educators deliberated how, and if, they should teach students to accept racial, cultural, and religious differences. After all, the ethnic makeup of America was quickly changing. The first wave of the Great Migration saw nearly 2 million African Americans move north and west to cities. While most classrooms remained segregated, even the whitest schools were increasingly mixed with the children of different immigrant groups.

In 1938, the New York City Board of Education began requiring students to learn about how multiple groups contributed to American history. When World War II erupted one year later, the demand for tolerance education spiked. The New York Times reported in 1939 that "Instances were cited of teachers in New York City and elsewhere being 'ridiculed, harassed and otherwise impeded' by pupils under the influence of, and stimulated by, Nazi doctrine." To nip foreign propaganda in the bud, schools across the country joined the tolerance movement. Military leaders encouraged it, too. They knew that American troops, many of them fresh out of school, would fight their best if they learned to set aside their differences.

Countless non-profit groups, many of them interreligious, led the charge. Burkholder writes that “Religious leaders, educators, and politicians stressed tolerance as a central tenet of democracy." They provided prejudice-fighting materials to schools, from teachers’ manuals to comic books to textbooks.

Outside of school, short pro-tolerance films played at the beginning of movies. People held tolerance rallies. The National Conference of Christians and Jews distributed 10 million “Badge of Tolerance” buttons. Groups such as the Council Against Intolerance in America distributed maps showing the breadth of diversity in America’s cultural landscape. Even Superboy stepped in, telling a bunch of his schoolmates that “No single land, race or nationality can claim this country as its own.” At the end, Superboy and his pals celebrate by eating Swedish meatballs.

The Superman comic that went viral was the handiwork of one tolerance organization: the Institute for American Democracy. Led by an Episcopalian priest, the Institute’s lineup of leaders resembled a walk-into-the-bar joke: Among its officers were a Catholic bishop, a rabbi presiding over the Synagogue Council of America, and labor movement honchos. The Institute’s goal was to “blanket the nation with poster, billboard, cartoon, and blotter advertising—expertly planned to ‘sell’ the American public a greater appreciation of the American Creed.”

And it did. Al Segal, a columnist for the Indiana-based Jewish Post, wrote in 1947 that the Institute was “hitting anti-Semitism and allied hates between the eyes in street cars, buses and newspapers all around the country.” In 1953, The New York Times called the Institute’s work “Do-Good advertising” that proved “mass media advertising can sell an idea, just as it can sell soap or chewing gum.”

Messages we can all agree on, right? Nope. This was the McCarthy era. Even the most pro-American advertisements couldn’t help being called un-American.

AN INTOLERABLE CONSPIRACY?

In 1948, California's Joint Fact-Finding Committee on Un-American Activities—a group of lawmakers charged with investigating disloyal and subversive citizens and groups—listed the Institute for American Democracy as a potential communist front. It claimed that the Institute had “numerous known Communists” on its governing body.

The committee complained that a truly American organization would speak explicitly against communism. Since the Institute didn’t scold communists, it was complicit with them. The committee further argued that the Institute, and other pro-tolerance organizations like it, had exaggerated America’s discrimination problems: “There is an attempt to spread the idea that forces of fascism are everywhere entrenched,” it stated.

A bigger problem was that the Institute was mostly subsidized by the Anti-Defamation League of B’nai B’rith, or ADL. The House Un-American Activities Committee was not a fan of the ADL.

The Anti-Defamation League formed in 1913 to combat prejudice against Jewish people. Between 1880 and World War I, approximately 2 million Jews had emigrated to America. By the early 20th century, restaurants, hotels, and clubs regularly barred Jews from entering their premises. Medical schools at Cornell and Yale placed limits on the number of Jewish students they would accept. (Yale’s medical school dean, Milton Winternitz—who was Jewish—reportedly told the school’s admissions officers, “Never admit more than five Jews, take only two Italian Catholics, and take no blacks at all.”) Even the U.S. military's medical advisory board casually stated that “the foreign born, especially the Jews, are more apt to malinger than the native born.”

By World War II, the ADL had joined the tolerance movement. It helped found and fund [PDF] organizations like the Institute for Democratic Education and the Institute for American Democracy, soaking citizens in calls for brotherhood. The groups aired radio shows telling the stories of famous Americans, such as George Washington Carver, and played them on more than 700 radio stations. It even lobbied the producers of the Superman radio show to insert democratic themes into its broadcasts. The group reached 63,000 schools, veterans groups, and private businesses.

Some legislators, especially State Senator Jack B. Tenney, chairman of California’s Un-American Activities Committee, believed this was a nefarious facade. Tenney, who was once nominated as a candidate for Vice President of the Christian Nationalist Party (which advocated racial segregation) and who equated [PDF] McCarthyism with “Americanism,” had once visited an ADL office and returned convinced their anti-prejudice campaigns were a Trojan Horse designed to brainwash Americans with Zionist propaganda. He believed the ADL was a gestapo-like cabal with communist sympathies.

LIFE magazine minced no words when it called Tenney a “notorious anti-Semite.” But his paranoia didn’t stop there. He didn’t trust Shintoism and used similar “Trojan Horse” arguments to justify the internment of Japanese-Americans. He wasn’t keen on Italians either. During World War II, the Tenney committee’s misgivings would help force 10,000 Italian immigrants in California to relocate.

As for the Institute for American Democracy, their ties to the ADL convinced Tenney that their loyalties existed outside of the United States. For that reason alone, an organization with the sole mission of touting American values was suspected of ... lacking American values.

Thankfully, that attitude didn’t last for long. In 1949, Tenney was on his way out of the fact-finding committee, which soon gave the Institute for American Democracy a clean bill of health, offering this mea culpa:

The committee’s 1948 report, under its general designation of Communist-front organizations, listed the Institute for American Democracy and the Institute for Democratic Education. The continuing investigation of these organizations reveals that both are sponsored by responsible individuals and groups of unquestioned loyalty. The programs … are in full keeping with the best American traditions and ideals and it is the design of the sponsoring individuals and groups to inculcate and preserve in the hearts and consciences of the American people love and loyalty for and to our country and the great principles of American liberty and democracy.

When you consider this historical context, the Superman comic becomes far more badass. The illustration appeared in 1949, one year after the Tenney Committee suggested the Institute for American Democracy was a communist front. Superman’s response? He steals the committee’s favorite accusation and slings it back in their direction: “That kind of talk is Un-American.”

As for Tenney, he’d later run for Senate in Los Angeles under the slogan “The Jews won’t take Jack Tenney,” a prediction that applied to Jewish people and, apparently, everybody else. Despite a plot to confuse voters by putting a mental patient who shared the same last name as his opponent on the ballot, Tenney still lost the Republican primary to 33-year-old Mildred Younger, a political activist who had never before held government office.
