Yes, it's about characterizing all accusations of antisemitism as being a "false flag" before any discussion happens. How can you know what will be said in future discussions? If all accusations of antisemitism in all future discussions are preemptively declared "false flags" that's a declaration that antisemitism no longer exists.

You may have been on the internet too long. The internet is filled with rationalizations for hate speech and you might have bought into some of them. The "anti-zionists" talk like antisemites, act like antisemites... take some to to consider whether anti-zionism is just a rebranding of antisemitism. Consider that all of the usual antisemites like Candace Owens are saying the exact same antisemitic conspiracy theories, but they're careful to use the word "zionist" where they used to say "jews". Consider that the people JD Vance has been talking to indicate the usual anti-semites that have now rebranded themselves as anti-zionists are being folded into the American fascist movement.

In these times it's important to establish some red lines you refuse to cross. Because they don't start with "Hitler was right" on day one. They make you hate a certain group of people and then expand that group over time. Fascists are pushing "anti-zionist" rhetoric, there's been a rise in attacks on synagogues and there's been a massacre of Jews celebrating Hanukkah. How long can you deny that these events aren't connected to the "anti-zionist" rhetoric you're seeing? You may believe there's a distinction between zionists and jews, but it's very obvious there's a lot of people committing violent acts that don't care about that distinction.

Why should I care about your rationalizations more than I care about the fact that "anti-zionist" rhetoric is resulting in violence against Jews? To me, if your rhetoric results in violence against Jews, your rhetoric is antisemitc no matter what you call it. Just more racist dog whistling by racist assholes.
