No, it DOES hold. And you know it. Because the conflation of antisemitism and anti-Zionism is just as dishonest as the conflation of racism with not kindly agreeing with every black person's "lived experience."
Even if you want to claim that all anti-semites are anti-Zionists, as I've already pointed out, you'd be wrong. Lots of Jews oppose Zionism and lots of anti-semites support Zionism.
Zionism is a political movement that used colonialism and racism to justify building a state on somebody else's land. All I know about you if you support that is that you're willing to discard your integrity if you think there's something in it for you.
