Israel is not Judaism and criticism of it is not criticism of Jewish people as a whole. To hold otherwise is to hold an entire people responsible for the actions of a few (those in the Israeli government), that those people often have no or only limited influence over, which would be an inherently bigoted position to take because it robs those people of their agency. If anything, the Israeli government itself is being antisemitic in a sense by pushing such a narrative in order to use Jewish people as a whole as a shield against criticism of their actions.
