Marcia Bronstein, regional director of the AJC Philadelphia/Southern New Jersey region, says the site, called "Translate Hate," was created on the heels of the organization's landmark study, which indicated that anti-Semitism has been on the rise for the past five years or so.
"It is designed as an innovative, digital resource that enables Americans of all backgrounds to expose anti-semitic tropes and then to take action against them," Bronstein said. "There are a lot of ideas that get shared and translated that are very problematic and create a lot of hatred and bigotry in the world and then create violence."
Some of the key findings in the study:
"That American Jews are deeply concerned about anti-Semitism and that it is spreading. Jews are hiding their Jewishness; they're concerned for fear and safety. And Jews consider anti-Zionism anti-Semitic."
Bronstein said the website makes examples of real tweets and news headlines and explains why certain messages can be harmful.
"It's almost like a glossary of anti-Semitic tropes and expressions," explaining why certain ideas are considered problematic, she said.
"There's a table of contents in Translate Hate, and it's alphabetical, whether it's 'blood libel' or 'dual loyalty' or 'greed,' 'Holocaust denial' — so everybody can see an A-Z listing. 'Zionist,' 'scapegoat.' There's a definition for all these things."
