Anti-Semitism is one of the oldest and ugliest manifestations of racism. It has followed the Jewish people from the day they became a nation until this very day. Classic Anti-Semitism took various shapes along the centuries from Anti-Semitism based on erroneous religious ideas to Anti-Semitism based on a perverted and noxious notion of racial science. In recent years, Anti-Semitism increasingly takes the form of anti-Zionism. However, since the Hamas attack on Israel the mask came off and we are witnessing the revival of old Anti-Semitism in its ugliest manifestations.
