Even in activist circles, this seems to be forgotten: It's not just Gaza, the West Bank, East Jerusalem... THE ENTIRE STATE OF ISRAEL IS PALESTINE.
The "recognition" from the UN in 1948 took place when most of Africa was colonized and many of the countries in the global south were essentially bullied into it. So it's all good that the world is on the side of Palestine, but Palestine is more than just the '48 or '67 borders or whatever
