judaism is religious ideology while zionism is political ideology. that is my take on the difference

Yes, but IHRA definition of antisemitism seems to include anything against the govt of Israel (there is controversy about this). So Israel govt says their activities are all about fighting antisemitism. So what they do is okay. We need to differentiate this to prevent bad govt actions being accepted

Ok ... But This confusion is an ambiguity maintained by the Israeli state which claims to be from a promised land (the Bible), an outdated book whose historical reality is only a legend!
