Anti-zionism is not Antisemitism. Zionism is not Judaism nor is it representative of Jewish people. Your conflation of the two is genuinely antisemitic.

Zionism is anti-Semitic at it's core, it other-izes Jewish people, and justifies the violent settler colonialim of Israel as in the defense of all Jewish people, which only serves to further fuel genuine Antisemitism at the expense of Jewish people globally. Zionism is also an inherently fascist ideology. The ethnic cleansing of the native people of Palestine has always been fundamental since it's inception as a colonialist movement. Adi Callai, an Israeli, does a great analysis of how Antisemitism has been weaponized by Zionism during its history.
