Another reason why the current wave of Left antisemitism hurts so much is that we just spent the past 20 yrs with DEI, antiracism, intersectionality, microaggressions, minority/indigenous/immigrant rights, etc. except now we see that NONE of that applies when it comes to the rights of Jews.
One of the reasons the Green Party motion hit so hard is because it confirmed something for Jewish ppl like myself that until now was mainly experienced in our personal lives, namely, many progressive friends going down anti-Zionist propaganda rabbit holes
