The Anti-Defamation League this week released a report showing that, in 2021, there were more antisemitic incidents in America than in any year since the group started keeping track over 40 years ago. "We've never seen data like this before, ever," Jonathan Greenblatt, national director of the A.D.L., told me. The rapid growth of Jew hatred isn't limited to the United States. According to a new report from the Center for the Study of Contemporary European Jewry at Tel Aviv University, antisemitic incidents were up last year in countries including Australia, Britain, Canada, France and Germany. Comparisons to 2020 might be misleading, because pandemic lockdowns likely reduced the numbers of antisemitic assaults and in-person harassment. But in several countries, including the United States, there were more antisemitic incidents in 2021 than in the prepandemic year 2019.
