For people who condemn the Greens, I want to know which of these is your view:
A - that definition of Zionism is incorrect, or - to be kinder - it's oversimplified.
Framing Zionism as racist against Palestinians because the Israeli government is violent against them oversimplifies the issues and erases how the Israeli government has been violent (even arguably creating apartheid structures) against some Jewish and other populations. It erases that political Zionism isn't the only branch of Zionism. Cultural Zionism and Religious Zionism existed before Political Zionism. Each of these have various subbranches and disagreements between different groups.
Political Zionism does have a racism issue. From the earliest political Zionist writings, they framed it as bringing Western civilization to the 'barbarians'. They included Eastern European and Mizrahi Jews within the latter - this wasn't a Jew vs Palestinian thing, Golda Meir famously discussed how her passport identified her as Palestinian. It was an 'enlightened' in a certain way creating a secure location for themselves, no matter what happened to everyone else. They categorized Jewish groups on ethnicity, religiosity, and other factors which is directly linked to some of the horrible treatment of those populations done by the Israeli government throughout its history to today. One of many examples - Israel bought Moroccan Jewish people from their government to work basically as indentured servants for years -- neither government comes out looking well in this.
Israel is largely build on political Zionism, a specific type that promotes a nationalist fervour to be violently supported. Many Israeli and Jewish groups have spoken out against this.
Hamas and the Palestinian National Authority have largely been build on Islamist nationalistic fervour to be violently supported who have been largely against 'self-determination' or democracy. Many Palestinian groups have spoken out against these authoritarian regimes. The horrible thing for many Palestinians is they are being oppressed by both the Israeli government and their own.
The British Greens not only provide an oversimplified definition of Zionism with no acknowledgement that there are multiple types of Zionism, their motion provides no evidence that their end goal - a single Palestinian state - would result in that state being a democratic state or the people being liberated with any of the motions they've listed.
The focus on Palestine Action, which has promoted violence, when there are so many other options supporting peaceful options like Heal Palestine, Realign Palestine, Builders of the Middle East just off the top of my head... it makes me question their motives - and who is backing them - even more.
there are no motions about the USA or Australia needing to hand back land and control to the natives.
As pp have said, there very much is and has been longer than the modern state of Israel has existed.
I'm Metis and I neither expect or would like British Greens to be involved in the conflicts that have been on-going with the Canadian or US governments.
The last time I was in a conversation on this with one who was discussing how important decolonisation and being pro-Palestinian is, she told me that 'Native Americans are jealous Palestinians still speak their own language". No idea where they got that idea from, all the ones I know are generally supportive of Palestinians even if not with any government involved. I could not find the words to express how sad it was that she had chosen division and spreading that kind of weird idea around in a way like she was trying to score a point about something, I'm not sure what, it came across like she was arguing Palestinians were better at being anti-colonial and that's why we should support them more.
