Right well see the thing is that if the antisemitism is just words on the internet and irony, then it's just a joke and you're overreacting if you say anything about it.
If the antisemitism is just words even if said to your face in person, then it's just words and you shouldn't let them rile you up.
If the antisemitism is just microaggressions and people taunting our kids in public schools, then it's just bullying and you should just ignore the bullies.
If the antisemitism is discrimination by not getting holidays off or having kashrus respected or having religious clothing banned, then it probably affects other religious groups just as much or more than us, so you should really be fighting for and centering them.
If the antisemitism is people using slurs or blood libel or other canards, it could be worse, you're just being a neurotic Jew; it's still just words, at the end of the day.
If the antisemitism is Jewish shops or establishments or synagogues being vandalized or threatened, then it's just a little broken glass and spray paint, it's not like anyone actually got hurt, y'know?
If the antisemitism is people shouting out genocidal rhetoric in their slogans and seig heiling in the streets at protests, well really what do you expect when Israel is committing a holocaust of their own?? (If the antisemitism is holocaust inversion then fuck you for trying to control the narrative; dontcha know lots of other people were targeted and killed by the Nazis too? How dare you try to monopolize this tragedy??)
If the antisemitism is violence-inciting rhetoric from religious or political leaders, that's just, like, free speech man.
If the antisemitism is stochastic terrorist shootings at synagogues and JCCs and day schools (etc.) then it's just lone wolf actors and it's part of a larger conversation on mental health and/or gun control; it's still too early to say we should address it on its own terms.
If the antisemitism is individual Jews being physically attacked for looking Jewish in public, that's really unfortunate but also are we sure they aren't Zionists? Because even if not they might have been asking for it by looking like Zionists.... and if they were, well can you really even call that antisemitism? Anyway it's not like it's a widespread problem and there are more pressing issues than antisemitism that we should address first.
If the antisemitism is widespread violence, discrimination, and an inability to safely express Jewish identity, then we should maybe issue some meaningless platitudes about how that's bad, but make sure to include how Islamophobia is also bad too even if it's not at all relevant to the conversation.
If the antisemitism is individual Jews being killed, it's still too early to intervene, because can we really call that systemic violence? We should be focusing on the groups experiencing systemic violence first.
If the antisemitism is pogroms, make sure to ask which side of the political aisle it's coming from first to determine whether it's worth using as additional tar for our enemies, and if it's not, best to sweep it under the rug in service of The Cause. But it's still not the right time to actually take a stand on it.
If the antisemitism is groups of Jews being attacked and killed, that's deeply unfortunate, but it still really can't be our priority when there's a genocide going on. (Also have you considered that maybe those groups of Jews deserved it or are lying?)
If the antisemitism is state-sponsored repression, expulsion, concentration camps, and/or attempted genocide, well, it's kinda too late to do much about it, you know? Why didn't you say something before now?? Why did you let it get this bad? No way can we do anything about it at this late stage; it's not worth risking our people over people who won't even speak up for themselves.
If the antisemitism is a successful genocide insofar as it seriously reduces the Jewish population for several generations, then really the question we should be asking ourselves is why didn't they stand up for themselves? Why didn't they fight back? Why did they go like sheep to the slaughter?
