'You seriously cannot turn up at any random location and say God gave me this land and I want it so now leave.'
Thats not what happened tho. I think its a common misconception. No one was initially expected to leave their houses. The intention was to give the Jewish nation a homeland, which I hope no one here technically objects to. Jew and Arab had lived alongside each other in varying degrees of peace and bloodshed for hundreds of years. Instead of 2 mixed nations with Arabs continuing to live alongside Jews and vv, the Arabs decided there was to be no space for Jews at all, and started a war of annihilation against the brand new nation of Israel ( still reeling from the Holocaust- can you even imagine ). If they had just accepted the borders then there would now be a mix of people with no one forced to leave their homes. But instead war was declared and Israel forced to defend herself. Violence ensued. Some people left their homes under threat of violence. Some people left of their own choice ( on both sides ) The Arabs who stayed in their homes are still in Israel now. How many Jewish people were also expelled from other nations all around the Middle East?
The birth of a new nation is always messy. A war always includes atrocities. A war by necessity opens the door to the absolute worst in us. Its not condoning such atrocities. Its just knowing the human psyche. The war should not have been started back in 1948. The local Arabs, accompanied by other Arab League nations started that war to remove every last Jew from Islamic land. What other choice did Israel have other than to fight back?
Theres an interesting mirror with the institutional racism in the US here.
You either accept black people are more likely to commit crime because of their innate nature, or you think to yourself, hang on that can't be right, you look into it and you discover more about the institutions they've grown up through.
You either actually believe Israel is a uniquely bad lot of humans or you look deeper into the reasons why they do what they do and try to understand the history.
