When Jewish couple Mikey Franklin and Sonya Shpilyuk hung a "Black Lives Matter" banner from the window of their condominium, they hoped to voice their solidarity with the social justice movement. Instead, the backlash to their small act of resistance was swift. Two days later, their car was egged and toilet paper was strewn across a tree in front of their property. A handwritten message, carefully spelled out in block letters, admonished Franklin and Shpilyuk for their banner and warned the couple to "enjoy the mayhem." At the bottom of the letter was a yellow Star of David and the word "Jude," German for Jew.With hate crimes on the rise, old coalitions between blacks and Jews are being rekindled and tested. According to a recent survey by theInstitute for Social Policy and Understanding (ISPU), 57 percent of Jews support Black Lives Matter, the second highest percentage of any faith group following Muslims. Although blacks and Jews worked closely to advance social justice during the Civil Rights Movement, the strong ties between the two groups have waned since the end of Jim Crow.But the election of President Trump has contributed to a marked increase in hate crimes, while racist and anti-Semitic attacks had already been on the rise for years. The FBI's 2015 Hate Crimes Statistics report showed that most hate crimes are racially motivated, with over half targeting African-Americans. Religiously motivated attacks rose nearly 23 percent compared to 2014, with the majority targeting Jews. Since January 2017, anti-Semitic hate crimes in New York have risen by 94 percent when compared to the same period in 2016. In March, army veteran and white supremacist James Jackson wasindicted on terrorism charges after traveling to New York City to allegedly kill black men.During the 1950s, the National Association for the Advancement of Colored People (NAACP) and Anti-Defamation League (ADFL) began to work as a united front on issues from segregation to employment discrimination. In 1965, at the height of the Civil Rights Era, Rabbi Abraham Joshua Heschel marched side by side with Rev. Dr. Martin Luther King Jr. from Selma to Birmingham. The image of the two faith leaders has been a longtime emblem of black-Jewish alliance. The story of Michael Schwerner and Andrew Goodman, two Jewish civil rights activists who were murdered in Mississippi along with James Chaney, a black activist, in 1964, is similarly notable. Their murder was the basis of the acclaimed 1988 Academy Award-winning film Mississippi Burning.But not all Jews view this golden age of black-Jewish relations as old allies reconnecting. Ma'Nishtana, a Brooklyn-based African-American Orthodox Jewish author and educator, believes this common narrative is a "romanticized and inflated revisionist history of how involved the Jewish community was during the civil rights era." Carol Greenberg, a history professor at Trinity College, also holds the view that Jewish support for civil rights wasn't entirely noble. "The meeting of the minds regarding the civil rights agenda emerged from a clear, explicit self-interest. Jews realized that their self-interest rested in making sure that the United States didn't discriminate against anybody. History showed them that if anybody went first, Jews were sure to come next."The closeness of the black and Jewish groups was not only a product of common moral and ideological beliefs, but also a function of proximity. Today, the term "ghetto" is used to refer to a poor, urban black community, but at the turn of the 20th century, ghettos in places like Harlem and the Bronx werealso home to immigrant groups and American Jews.As Jews became more upwardly mobile, Greenberg said, "they benefitted from white privilege even though they didn't know it, and failed to recognize the structural barriers preventing black people from doing better economically. They began to push a kind of race-blind approach to society." The growing divide between the two communities was crystallized in Regents of the University of California v. Bakke, a controversial affirmative action case that marked the first time black and Jewish groups filed amicus briefs on opposite sides of the same question.Divisions between the two groups became further entrenched as black activists embraced an anti-imperialist message and American Jews embraced loyalty to Israel, according to Marjorie Field, a history professor at Babson College. "After 1967, when Israel began its occupation of the West Bank and Gaza, the Third World Movement began to focus too on Palestinians, and so too did some black Americans," she said.Today, Israel continues to be a flashpoint of conflict between blacks and Jews. In August 2016, the Movement for Black Lives, a national umbrella organization encompassing over 50 organizations, released apolicy platform titled "A Vision for Black Lives." The document, which touches on issues including criminal justice and education reform, also includes a statement on Israel and Palestine:
