The word was not coined in the 1940's. Just because the great tragedy of the Nazi slaughter was correctly described as a holocaust, we cannot exclude all past and future holocausts from this nomenclature. In the same vein, it is unfair to insist that "anti-semitism" can be only used to describe anti-Jewishness. What can one call the gut hatred of other ,non-Jewish semites?
