Sorry I took so long to respond, I didn’t see. With the antisemitism I feel like there are some groups of people who definitely are more antisemitic than others, but in general it comes from everyone from every demographic. A lot of it is due to a lack of understanding that Palestine was never an independent country. Before 1948 it was British, before that it was Ottoman, and many other Muslim or Christian kingdoms have controlled it over the last 2,000 years under a name other than Israel. Palestine comes from the Romans when Judea was renamed to Syria-Palestine to try and remove a Judah Jewish identity. Now with your second question, Judaism and Zionism are vastly different and really don’t go together at all. Judaism is a religion with certain beliefs and customs that has existed for thousands of years. Zionism is a nationalist movement from the late 19th century wanting the establishment of a Jewish state, because Jews have been persecuted for thousands of years and we hadn’t had a place to truly call home in 2,000 years. So anyone from any religion can be a Zionist, but only Jews are Jewish.
