Liam Hoare writes in the Forward:
The reason for this disparity between perception and experience, however, is not groundless panic or hysteria; it comes because of new manifestations of anti-Semitism, principally dissemination via the Internet and new media.
When asked where anti-Semitism against Jewish communities occurs, 75% of European Jews pointed toward anti-Semitism on the Internet above all else, followed by 59% for anti-Semitism in the media. Internet anti-Semitism today is considered a greater problem than the desecration of Jewish cemeteries, the vandalism of Jewish buildings or institutions, and expressions of hostility toward Jews on the street and in other public places.
