I disagree. I don't think it is anti-semitic to question the legitimacy of Israel, because it is a disagreement or criticism of one aspect of the beliefs of a proportion of Jews. You would end up labeling everybody "anti-this and anti-that" just because they disagree with certain elements of another's views or way of life. I'm not saying these two are in any way equally legitimate, but disagreeing with the legitimacy of the ISIS Caliphate is not anti-Muslim, and for me the same is applied to Israel. Just because a proportion of a people say it's their view and major belief, doesn't make you anti that entire group of people because you disagree. I disagree about a number of elements of Jewish practice and faith, that isn't anti-Semitism.
In fact your definition is something I would expect Netanyahu to use as a way of trying to ensure nobody could argue against his policies because if you disagree with any of it you're "anti-semitic, hate all Jews and everything associated with them". It's a definition to be used by very single-minded, bigoted people who want to believe their view and their way is the only way and everyone opposed to it is a "hater".
