What I have seen is a confusion (perhaps intentional) between anti-semitism, and protesting Israel’s behavior since the Hamas attack in October.
Criticizing Israel’s response is not anti-Semitism- it is literally just criticizing the response.
Okay - then what should be Israel's response? For me what they are doing is the bare minimum with the minimum casualties from the options they have. Hamas is Gaza's government. Hamas has intertwined the civilian and the military infrastructure. Hamas has made sure that the civilian Palestinians will suffer if you target Hamas. And it was Hamas that made sure with organized rape, torture and atrocities on Oct 7 that it can't be overlooked or forgiven.
Here is a good rule of thumb - if you are going to stir shit - stick to just killing. Don't livestream torture and rape, so diplomacy will have something to work with.
The same response I have concluded should have been the US' response to 9/11: turn the other cheek, and invest heavily in reconciling with "enemy" forces while rebuilding "enemy" infrastructure and institutions, while dealing with individual bad actors on a case-by-case basis as a matter of legal (rather than martial) procedure.
And I'm not joking.
I feel bad for Israelis who have let their government doom them to a generation of government mismanagement and expensive, arduous military adventure. My single-payer health insurance and my friends' free college education went into a couple Patriot missiles, and I do wonder what they're going to have to give up.
