The ironic thing is, conflating any and all criticism of the state of Israel with anti-semitism could be argued as anti-semitic itself, because to suggest that jewish people in general and the Israeli state/military are one in the same such that criticism of the later is also hateful towards the former, is also to suggest that jewish people as a whole are responsible for the actions of Israel.
As cultural groups as a whole are inherently unable to be guilty of crimes (since even if a large number of people belonging to one commit some crime, such a group will also contain members that cannot be guilty of it, like young children), but states and similar entities, being organized and capable of decision-making, can be, then any attempt to link the moral culpability of a state and that of a cultural group is inherently to apply unfair accusations to that group, and thus hateful to it.
