Why do some celebrities support the Israeli government in the current conflict with Palestine?

UPDATE: Thanks everyone who engaged with me, I’ve really appreciated every opinion that was commented! I now am of the belief that both sides are immoral and unreasonable, and I understand the conflict in a lot more depth. It makes sense why both sides have supporters but I can’t personally justify the actions of either as they have both committed recent and unnecessary atrocities in the name of their causes. If you’re curious to understand the conflict better, read through comments I replied to in order to hopefully understand what gave me this opinion, it was a bit of a rollercoaster.

I’ve seen celebrities be “cancelled” and rejected by fans for supporting both sides of the conflict which has confused me. Here’s how I understand it:

Israel has restricted Palestine’s freedom for a long time and oppressed their people, with many more Palestinians dying in the conflict than Israeli.

Hamas, acting on behalf of Palestine but with no connection to their government, committed terrorist attacks on Israel’s people.

The civilian population of both countries dont deserve what has happened to them, obviously, but here’s what I don’t understand: The Palestinian government itself doesn’t seem to be in the wrong while Israel’s does, for not letting Palestine be free. My understanding may be very flawed which is why I ask here but that’s what I’ve been able to understand.

Why have many celebrities, such as Mark Hamill, been supporting Israel, while their actions actively oppress Palestine?

Edit: Sub is called no stupid questions, I clearly don’t know what I’m talking about but have tried and am still trying to learn, why the downvotes?
