From Wikipedia:

Zionism[a] is an ethnocultural nationalist[b] movement that emerged in Europe in the late 19th century that aimed to establish a national home for the Jewish people, pursued through the colonization of Palestine,[2] a region roughly corresponding to the Land of Israel in Judaism,[3] with central importance in Jewish history. Zionists wanted to create a Jewish state in Palestine with as much land, as many Jews, and as few Palestinian Arabs as possible.[4]

Why should any religion have a nation? This is European Jewish people that have been European for multiple generations back a millenia saying that Palestine belongs to them and whose objective is basically to wipe Arab Palestinians off of Palestine through colonization and force. The movement of Zionism was started by people that are no more Semite than any other European Caucasian person at this point.

The whole movement of Zionism requires Palestinian genocide.

Jewish people deserve to be safe and deserve to have somewhere safe to be. But, Zionism isn't the right way.

EDIT: Just to clarify, I am against the idea of any ethnocultural state whatever it may be. This shouldn't be a thing. Jewish people however deserve to be safe anywhere. But it shouldn't require an entire people to be displaced or killed for them to be safe. This is ridiculous.
