That's the etymology of the two roots of the word, but it's not the English definition which specifically refers to discrimination against Jews. The word is from a German term which was created by an antisemite in order to make his hate speech sound more reasonable.

I say this in no way to discredit your argument against the conflation of anti-Zionism with antisemitism. It's possible to be critical of Zionism without being antisemitic.
