So it was more than a little shocking to see Billy Joel wear a yellow star on his jacket during a concert a week after the violent white supremacist rallies in Charlottesville. After all, Joel is not the first artist who comes to mind when you think of bold or provocative political gestures. It’s been his luck and his curse to be wildly popular while rarely courting controversy or inspiring deep critical analysis or respect. The critic Chuck Klosterman wrote famously that Joel “has no extrinsic coolness. If cool were a color, it would be black — and Joel would be kind of a burnt orange.”

His wearing the star should have been the wrong thing to do in so many ways. Jewish groups are always worried about appropriations of the Holocaust and carefully designate the boundaries of acceptable Holocaust analogies (that is, none). The same week that Joel wore his yellow star during the encore at one of his regular Madison Square Garden gigs, the fashion house Miu Miu discontinued a clothing line that featured a yellow star that was only reminiscent of what the Jews were forced to wear (the World Jewish Congress had complained). Earlier this month, the Donald Trump mouthpiece Jeffrey Lord lost his commentary job on CNN essentially for calling one of Trump’s liberal critics a Nazi (and presumably casting Trump’s defenders in the role of the Nazis’ victims).

But if any Jewish group had a complaint about Joel’s gesture, I haven’t heard it. The singer’s gesture came across as sincere and pointed, not tasteless.

Although he didn’t say why he wore the star, his ex-wife, model Christie Brinkley, took to social media to write that the star symbolized the “painful, no excruciating, memories of loved ones who wore that star to their death.”

“Thank you, Billy for reminding people what was … so it may never ever be again,” she added.

Although Joel has never made much of his Jewish background, he has talked of his father, a German-born Jew who, according to Joel’s biographer, had vivid memories of the Hitler Youth and SS training near his childhood home in Bavaria, and who lost relatives in the Shoah.

Joel’s gesture might have been especially meaningful because his Jewishness, as he once put it, stopped at his bris. The star seemed to be saying to the neo-Nazis who gathered in Charlottesville — and the political figures, ahem, who seemed unable to fully condemn them — that even he, a secular celebrity and multimillionaire, would still have been a victim of their perverse ideology. The Nazis made the Jews wear the yellow star so they couldn’t hide. The stars on Joel’s lapel and back seemed to say “I’m not hiding. I can’t hide. Come and get me.”

But at least Schulman, like Joel, is Jewish. I can’t think of a non-Jewish celebrity who could get away with wearing the star. They’d be accused, rightly, of appropriation, the way the artist Dana Schutz was excoriated by black folk after her painting of the mutilated face of Emmett Till — a 14-year-old who was lynched by white men in Mississippi in 1955 — was shown at the Whitney Biennial in March. Critics of Schutz’s painting said the circumstances and symbolism of the black teenager’s death are still too raw to be translated by a white woman into art.

That’s not to say (or at least I wouldn’t say) that only members of a particular ethnic group or religion can depict their own suffering. (What is widely considered the most powerful anti-lynching song, “Strange Fruit,” was written by a Jew, Abel Meeropol, although it was Billie Holiday who sang it most famously.) But certain gestures of interethnic solidarity — “Anne Frank, c’est moi” — are landmines. Writers from William Styron to Yann Martel have been accused of cheapening the Holocaust through allegory or by universalizing the Jews’ suffering. Jewish artists like Art Spiegelman or Agnieszka Holland are given the latitude to depict the Holocaust in ways that might seem misguided or offensive if done similarly by a non-Jew. Authenticity can be earned, although it’s a lot easier to be born with it.

History’s most famous appropriation of the yellow star, meanwhile, turns out to be a myth. The U.S. Holocaust Memorial Museum states flatly that “there is no truth” to the story that Denmark’s King Christian X wore a yellow star in solidarity with the Jews. Instead, the museum tells us, the king was heard to say to his finance minister, “Perhaps we should all wear it.”

If this were 1941, the answer would be yes — everyone should wear it. In 2017, everyone should at least imagine what it would be like to be persecuted because of their race, religion or nationality, and what it might feel like to be literally marked for death. I think that’s the kind of empathy Joel tried to inspire.

Very cool.
