"Antisemitism is an umbrella term for what is a variety of negative beliefs or actions held or taken against Jews for the sole reason that they are Jewish. Its history is long, earning it the designation “the oldest hatred.” Although there have been many causes, philosophies, and manifestations of antisemitism over the millennia, they all share in some level of hatred, contempt, or disdain for individual Jews, Judaism, or the Jewish people.
The term “antisemitism” is complex. Although, as noted, the animus of antisemitism has been long held, the term itself is relatively new."
