Israeli people and Palestinian people both have a legitimate claim to live in the land surrounding Jerusalem. Palestinians are mostly muslim, and there are other muslim places to live. Israeli people are mostly jewish, and there are no other jewish places to live. That said, religion isn’t ethnicity. Palestinians may be the same religion as other muslims, but they’re not the same race. Just like black americans are mostly christian, but that doesn’t mean they’re the same race as white americans. Israeli people can’t be guaranteed fair treatment elsewhere. Palestinian people have a right to live in their homes.
Israeli and Palestianian people both have a valid and important need to live in the holy land. So the simple solution is, they should both live there. That’s a solution supported by a lot of Isreali and Palestinian people. But it’s not a solution supported by the government of Israel. The government of Israel wants political control over the whole region, and to be able to legally and systemically put jews first.
I don’t think the correct answer is “support” or “don’t support”, because that’s too broad. I think the correct answer is to support the people’s rights, and support the government’s desire for safety for its people, but not to support the government’s treatment of palestinians.
