An anti-Zionist lefty told me today he only hates Zionists, but he loves Jews. And he was genuinely puzzled why I didn't become an Anti-Zionist Jews with Trump and Netanyahu derengement syndrome in order to be loved by the radical Left.

--- here is my answer:
There are a lot of wrongs in your assumption.
Left wing antisemitism is different from Nazi antisemitism. It is not based entirely on race. Nazis say Jews are an inferior middle eastern race, that can contaminate the racial heigine of the superior Arian race therefore it must be exterminated.
Left wing antisemitism is more similar to the Spanish Inquisition. You can repent by converting.
Left wing antisemitism is based on Marxist oppressor / opressed duality, who put the Jews, even woman being raped in a music festival, as oppressors. + It is projecting the sins of the colonization of America on the Jews of Israel.
I.e. A Jew can be accepted to the Anti-Zionist Leftism only if he converts to anti-Zionism and sells his brother and sisters. But even if Jews are converted to anti-Zionism, they will still be at the bottom of the Woke pyramid as being privileged whites.
I believe Israel exists. This is a fact. And I believe Israel has a right to defend itself from Jihadism that seeks to exterminate most of the Jews except for young women to be raped as sex slaves. The war against Jihadism is a war to survive. And being an anti-Zionist woke Jew and see my brothers and sisters slaughters and raped is not appealing to me.
I don't want to abandon my family to Jihadi death-cults for the 'privilege' of converting to anti-Zionism leftism to be accepted by them.
I'm sorry. But I have a spine.
