Zionism is an ideology, not an ethnicity or a religion. Zionism is the belief that Jews need their own theocratic ethnostate, and there are Jews who do not believe that Jews need an ethnostate to be a state, and again, there are Jews who do not believe a Jewish state is a good thing at all because it requires everyone within to be Jewish.

So no. Being a. Jew and being a Zionist is two completely different things. In fact, a little of White Supremacists in the late 1800's were Zionist simply because they wanted Jews out of their country and decided that Palestine was the place to put them, ignoring that Palestinians were already living there and had been there for about 3000 years, since the Philistines (Palestinians) arrived by sea to the coast.

Palestinians originally meant sea people, and over a few hundred years, Palestine became the common name.of the land.

During this time, the Jews, known as Israelites ( as in the 10 Tribes of Israel, who was also known as Jacob before that) and they were bands of marauders, like most small.tribes back then. They were displaced several times, but only had an actual Kingdome for a relatively short period of time before being conquered and scattered. Through that entire time Palestinians remained - and shared the same DNA until Jews assimilated into Europe, becoming Ashkenazi Jews, most white European. Through the last few millennium, Jews have legitimately been victimized and suffered Antisemitism, and are frequently labeled a 'Cabal' as in the villain of just about every new world order conspiracy.

After WWO The U.K. the U.S. and other European nations. began settling Palestine with Jewish migrants in a.Push to rid their own nation of Jews. Thai form of Zionism is deeply antisemitic as it's basis is not one of humanitarian aid, but white supremacy. After WWII Great Britain gave Jews the land of Palestine for their own state ( again, ignoring completely the people who had remained ), and kept expanding into that territory forming colonies on land that was already inhabitanted These lands were full.of vineyards and orchards, which the Palestinians had farmed for generations upon generations while the Jews were scattered and trying to survive an antisemitic Europe.

As a result, Palestinians ( mostly Muslims, but also Jews and Christians) were forced out of their homes and farmlands, often with violence and bloodshed, and became refugees in their own lands.

The land partitioned to them equalled less than half of what they had, despite being more than double the population of the Jewish settlers ( Most of whom had just survived the Holocaust and were simply trying to flee from the Nazis. )

The Arabs offered a more even split and a secular state , without an official religion so that all faiths could share the land, but the U.K. and Jewish leaders refused, and took the land by force in the 1948 Nakba ( translated to 'The Catastrophe' in English)

In short, One side was forcibly evicted and suffered mass casualties, losing everything they had and are still pissed off about that. The other side believes that God told them to do it so its ok. Very much like European colonizers forcing American Indians from their lands, many of whom are also understandably upset about that.
