Arab and Islamic apologists have in the past tried to claim that they cannot be anti-Semites, since they themselves are Semites. Of course, the word was originally coined by the German anti-Jewish agitator Wilheim Marr as a pseudoscientific-sounding alternative for “Judenhass” (Jew-hatred), when he founded his Antisemitenliga in 1879. Marr was only concerned with Jews and not at all with any other Semitic people, and in practice the word has never meant anything other than bigotry against Jews.
I have always preferred the unambiguous alternative “judeophobia”. My daughter wondered if it was patterned on the word “homophobia”. In fact, the word “judeophobia” was first proposed in 1882 by the physician and proto-Zionist activist Leon Pinsker, in his pamphlet Selbstemanzipation (Auto-Emancipation):
A fear of the Jewish ghost has passed down the generations and the centuries. First a breeder of prejudice, later in conjunction with other forces we are about to discuss, it culminated in Judeophobia.[…]
Judeophobia is a psychic aberration. As a psychic aberration it is hereditary, and as a disease transmitted for two thousand years it is incurable.
He goes on to explain the irrational character of judeophobia (a phobia, medically speaking, being exactly that: an irrational fear), its foundation on superstition, and the futility of any attempt to “cure” people of it by rational argument. He then goes on to make the same case as Theodor Herzl would so famously do fifteen years later.
Pinsker has been nearly forgotten outside Israel and well-read Zionist circles (as he never commanded the readership and contacts of Theodor Herzl) but he is remembered by the many Pinsker Streets in Israeli towns.
