hang on, how are you defining 'zionist'?
the jewish centre for justice defines it like this
Zionism is the belief in the Jewish people’s right to self-determination in our ancestral homeland of Israel. It affirms that Jews, like all peoples, have the right to live in safety, dignity, and sovereignty in a nation of their own.
that just sounds like being pro-Israel to me?
feels like you are not showing all of your working here. if you state some of your assumptions it might help other posters to understand where you're coming from
