Please don’t blame Israel for antisemitism. There is literally nothing Israel could ever do to justify antisemitism.
Blame Israel for what they are doing to Palestine. Give Israel it’s much deserved consequences for war crimes and genocide.
Blame antisemites for antisemitism. Ethnic hatred is unjustifiable.
Look, the Jewish People are both defined by ethnicity and religion, but the way you speak of that dynamic shows a profound ignorance of it. This isn’t some Israeli conspiracy, most self-identified Jews are at least somewhat ethnically Jewish. Not all are religious, though many respect tradition regardless. That ethnic group historically originated from the Levant, and Judaism as a religion views the Levant as a holy land.
The only real Judaic aspect of Israel’s war on Palestine is Zionism, which can range from the belief that an Israeli has a basic right to exist in the Levant (alongside others), to the belief that Israel should dominate the Levant (and expel others). Netanyahu is on the latter end of that spectrum, and supports mass violence against and forced displacement of Palestinians to meet that end, which is indefensible. We cannot accept Israel, U.S. ally or not, to be engaged in a holy war.
But anyone deciding to point the finger at Israel when they encounter real-world antisemitism isn’t actually making a statement about Israel. They are deflecting blame away from bigots, and suggesting that they might at least have some excuse for their hate. I don’t have any tolerance for that.
