Antizionism ≠ opposition to the Israeli politics. One can be Zionist and against this genocide, against colonization, against Netanyahu and for a Palestinian state. Antizionism is an opposition to the right of self determination for the Jewish people, and that's antisemitic.
The issue is that they get used interchangeably so often that there's really no difference these days. My wife is Jewish, Canadian and has zero interest in politics, Israel or the middle east, which she has never been to. She still gets called out for Israel's bullshit as if she cares or has anything to do with it
That's because anti-zionism is used as an excuse to be antisemitic more than it's a legitimate criticism of the Israeli government or state. It's the "I have a black friend" of Jewish hate.
Antisemites hardly need to hide behind anti-Zionism when there are plenty of antisemitic Zionists. It would be counter-productive if they did, because antisemites would love to see Jews removed from their country, and why not removed to Israel?
