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.
So what should Israel do specifically in Gaza?
The conflict is not limited to Gaza. In the West Bank and East Jerusalem, Israel continues to build its illegal settlements, to subject the Palestinian population to a humiliating and brutal military occupation, and to kill Palestinians regularly (several hundred in the West Bank this year).
Until Israel leaves the occupied territories and allows the Palestinians to live as normal people, there will be Palestinian resistance. A few years ago, the people of Gaza tried nonviolent resistance, protesting at the border fence. Israel responded with live ammunition, killing hundreds of protestors.
The Palestinians have tried every way to obtain their freedom: protest, negotiation, armed resistance. Nothing works. Israel is, by far, the stronger party, and it does what it wants to the Palestinians with no consequences.
Israel is stronger than Palestine, sure, but that's not the most relevant comparison to think about. Think about all the neighboring countries that do not recognize Israel's right to exist. Think about their financial and military support for Hamas. Think about all the extremists that come from Syria and Iran to help Hamas.
