I won't call him "anti-Semitic," since Arabs are Semetic as well. I will, however, call him a Jew-hater. He's a hard-core leftist, and a core belief of hard-core leftists is hatred of Jews.
For instance, the Soviet Union's Communist Party, though they hated and oppressed Jews, also refused to allow Jews to emigrate, and often jailed Jews who expressed an interest in leaving the Soviet Union.

Anti Semitism has nothing to with”semites” or who is “semetic”.
