Yes, Jill's article is very well balanced and written! As far as this professors opinion however, I think that Dennis Prager, a political and religious commentator in the US says it well: Imagine someone saying that he seeks the destruction of Italy because he regards Italian national identity as racist. Further, imagine that this person constantly denies being anti-Italian, because he does not hate all Italians, only Italy and all those who believe Italy should exist. Now substitute "Jewish" for "Italian" and "Israel" for "Italy" and you understand the absurdity of the argument that one can be anti-Zionist but not anti-Jewish.
