Perhaps I shouldn't dance around the point.

It is true that many Jewish zionists dishonestly equate anti-zionism with anti-Semitism.

However, this only works because Nazis, the KKK, and other anti-Semites have been using "zionist" as a dog whistle for "Jew" for literally longer than I have been alive (I am in my 40s).

This is why anti-zionist Jews are tetchy about non-Jews calling all violent counter-protestors (many of whom are anti-Semite fascists themselves) "zionists".
