The Israeli government is murdering children and committing war crimes, and they’re upset about what The Onion has to say about it.
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.
