For years, Meta has allowed its 3 billion users around the world to employ the term “Zionist,” which refers to supporters of the historical movement to create a Jewish state in the Middle East, as well as backers of modern-day nationalism in support of that state and its policies.

Meta’s internal rules around the word “Zionist,” first reported by The Intercept in 2021, show that company moderators are only supposed to delete posts using the term if it’s determined to be a proxy for “Jewish” or “Israeli,” both protected classes under company speech rules. The policy change Meta is now considering would enable the platform’s moderators to more aggressively and expansively enforce this rule, a move that could dramatically increase deletions of posts critical of Israeli nationalism.

“We don’t allow people to attack others based on their protected characteristics, such as their nationality or religion. Enforcing this policy requires an understanding of how people use language to reference those characteristics,” Meta spokesperson Corey Chambliss told The Intercept. “While the term Zionist often refers to a person’s ideology, which is not a protected characteristic, it can also be used to refer to Jewish or Israeli people. Given the increase in polarized public discourse due to events in the Middle East, we believe it’s important to assess our guidance for reviewing posts that use the term Zionist.”
