Sure Jup will answer your question in her own way etc as that post was theirs
I can't answer for her and she will have her own thoughts or opinions etc that may differ from mine.
My opinion is this:
*It isn't antisemitism to criticize the Israeli government so long as you don't use Jewish related words or phrases or tropes. So no nazis, holocaust, etc
*If you ask for the dismantling of a state containing 9 million Jewish & Arab people that is effectively asking for ethnic cleansing or genocide. Which is exactly the same as some say Israel is doing. Most those citizens especially the middle eastern Jews have already experienced this in their own states. So it can be argued this could be antisemitism
*The use of the word Zionist if used to replace the word Jew in old revised nazi propaganda as we have seen in older protesters is antisemitism
The use of the word Zionist is most the time used wrong anyway. Zionism is part of the daily prayer religious Jews say every day and has been for hundreds of years.. The belief to live somewhere safe and be free to just be Jewish. There is a Zionist movement that is more political and that is what most protesters are talking about. So they should say political Zionism or just the Israeli government. However some like to use the word Zionist like it is an insult. Whereas it really isn't because around 84% of the world's Jews are Zionist. They all vary in opinion from being anti Israeli government to being very pro Israel government plus everything inbetween. Most people that are anti Zionist normally fall into two categories, they don't actually know what a Zionist is other than social media rubbish or they are antisemitic
Also everyone thinks that modern/political Zionism was a European endeavor, but the OGs of this Zionism are Yemeni Jews who made the dangerous track in 1868, 30 yrs before the first world Zionist congress. They built roads, cities, fought in WWIII, and had a massive impact on Jewish life in Israel.
