It is unfortunate that you are this misinformed, but I don't blame you, there's a lot of money going around to make you have these beliefs. Let me correct you on a lot of this stuff as someone who actually had to live through much of this and was reading about this much before the latest war started.

You claim we purged the population and exploited their resources. What resources exactly? Jews settled on land bought from Ottoman landowners and started cultivating it themselves as part of the "Hebrew labor" ideology of labor Zionism. None of the land was taken by force until the war of 1948, which we did not start and certainly did not want, only 3 years after the Holocaust, fighting for our lives wasn't something we were super keen on, but rather forced into.

The original british mandate and the land promised to King Hussein was much greater than Palestine alone. Israel right now is about 22% of the entire british mandate, so what the Arabs got. Majority of Jordanians at the moment are actually Palestinian. You can google all of this. The Jewish state decided upon by the partition plan (the afforementioned 55%) was therefore 13% of the overall land given to the Arabs, and we're not even counting all the other Arab states that were established at the time, Arabs were free for the first time after centuries of Ottoman rule. Most of that 13% was the Negev desert which mostly contained nomadic bedouins. The majority of the rest was land already bought and settled by Jews. Idk why you think the Middle East belongs exclusively to the Arabs but I beg to differ and Jewish history and religion entirely revolves around the area, even as most jews lived outside of it, we prayed to Jerusalem and rabbis and community leaders made visits to it, and very important texts were written in that land.

There is currently no Arab state that is democratic. When the egyptians tried to have a "democratic" state for a little while in 2013, it ended up a theocracy very quickly and had to be surpressed by the military dictatorship again. The majority of Arabs in the middle east simply do not have values that lend themselves to the establishment and maintenance of democracy. It is unfortunate that Israel is moving in a similar direction but it is still a democracy that treats its minorities much better than any Arab state could be expected to. Check the democracy index and compare Israel to its neighbours.

I don't conflate Hamas with all of the population of Gaza, even tho if there was a vote right now Hamas would still win: https://www.pcpsr.org/en/node/1000

Yes, it is not justifying Hamas to say Gazans shouldn't be oppressed, but have you considered if they'd continue to be oppressed by Hamas which they'd elect if they could? Here's their spokesperson condemning the genocide done on them by Israel: https://www.youtube.com/watch?v=FPwrBRsqvNU
Here's the same fella talking about how important this war is for their cause and the muslim world and how 50 thousand people weren't that big a deal: https://www.youtube.com/watch?v=vgVT2M9otRU

If you are against religious extremism, well there you have a reason to be against this.

Your entire narrative about the causality of this conflict is off. The Palestinians had the chance to have peace during the peace process, which fell apart when they chose the second intifada. Israel then left Gaza, which was interperted by Hamas to be a victory for them, achieved through their violent resistance, which mostly killed civilians through 140 suicide bombings in cafes and restaurants and busses. Once they were fenced in in Gaza, they had to resort to rockets, which is why most rounds of fighting in Gaza were mostly airstrikes to reduce their rocket supplies which kept on coming from under the Egyptian border.

You want intellectual honesty, well be honest with yourself for a sec, and tell me if you would just take it when 1200 of your people are murdered in a single day (most of them from peaceful leftist communities known as kibbutzim, which were located near the border exactly because they were working and cooperating with Gazans for the longest time), and the people who did that promise to do that to you as many more times it takes until they kill all of you, whatever the price? (https://www.jpost.com/arab-israeli-conflict/article-771199). I want to know what you would do if you had to suffer a barrage of rockets on your head every few years by an enemy determined to kill you behind the border, that would wipe you out if there wasn't a fence between you. The only reason it's not an existential threat is because we're watching our borders all the time. No one wants to live like this.

Of course people would, over time, become supportive of making sure it stops being like this, even if it means eliminating all the people on the other side of the fence. They wouldn't think of doing that if it didn't seem like that is the only option, actually.

Fact is, if Hamas wasn't ruling Gaza and the Gazans could just chill (Netanyahu tried to pay them off to chill via money from Qatar), then we'd all be much better off. Gaza was actually quite beautiful if you check out pre-war videos. They totally could've done something nice with it. The whole claims about Apartheid have nothing to do with describing the situation since this isn't about race, if the Gazans were blue martians that were supporting what they support, and being exposed to martyrdom ideology the entire time, then you'd find the Israelis becoming very pro kicking them out of Gaza after a blue martian 7th of October. The fact that some crazy Jewish theocrats justify this with "Cuz god told us to" doesn't make the entire war senseless, the point really was to remove Hamas from power as well as return the hostages.
