That bit is sarcastic hyperbole. Often we're seeing people and media orgs who are anything shy of sycophantic to the Israeli government get accused of antisemitism.

The guardian has been better than most but they're still doing a lot of laundering of genocide and settler-colonialism in their coverage. I am frustrated by stuff like the passive voice diminishing that literally every civilian dead and aid convey bombed is an activity policy choice. Jestingesting that to reduce it to mere reaction is to deny the Jewish people in government human qualities like agency and a moral compass.

Which I think there is a kernel of truth in.

edit: awkward phrasing, I think there is a kernel of truth in the idea it's antisemitic to believe that Israeli people/the state somehow are less morally culpable because of the horror visited in Jewish people on the past/the present to a lesser extent.

If I can attempt to explain what I thought @NaevaTheRat@vegantheoryclub.org was doing (certainly, it's how I interpreted their initial comment), it's that they were playing off of the very, very common refrain from Israel and its supporters that any criticism of Israel is antisemitic. Sometimes they'll be quite explicit about that, but they'll also often pretend otherwise while levying the "antisemitism" critique at anyone who calls out the actions of the state of Israel.

A reasonably common response to this is that actually, no, that is itself antisemitic. Because it's implicitly tying the actions of one country with the Jewish people. And so the Israeli government and its supporters are being antisemitic when they try to deflect blame for Israel's actions by calling the blame antisemitic.

Naeva was doing something kinda similar to that here. Except this time instead of being about deflecting the blame, it was about how the article implicitly phrases it as though Israel had no choice but to commit genocide. It was just automatically triggered by the Hamas attack.
