Gaza is the world's largest open air prison.
Um, no. I know this gets repeated a lot but it is wrong. The West Bank is an open air prison. Gaza was an autonomous zone with neighbors (including Egypt) who don't like them. Gaza wasn't an open air prison, but it will be now. Also, your claims about losing land in 1948 don't really wash. 99% of both populations were not in the Levant in 1900. That area was worthless after the Silk Road stopped being a major trade root in the early modern period. So most people left and Ottoman administrative incompetence did the rest. After WWI, small numbers of both Jews and Arabs moved into the region. After WWII, many Jews from Europe went there but all the Jews from the Middle East and North Africa were forced at gunpoint to move to the Levant. When they got there, the British (not the Jews) were moving the two populations into different areas to prevent conflict. There were atrocities (by both groups) but only one of those groups was moved there by force and it wasn't the Palestinians (who didn't use that label yet). Truth is, this style of conflict is endemic to this area since 1100 or so when terrorism became a common tactic. And it is largely only practiced by the Muslims. Also, I am being nice here, there is a lot of history I am leaving out and none of it makes the Palestinians look good.
Being in favor of mass civilian deaths is hardly strong morality
So you are anti-hamas then right? right? That's an absurd way to characterize this conflict. I could say that trading with China is being pro-genocide of the Uyghars but Apple still makes the iPhone in China. Also, the number of total deaths in Gaza is less than a week of the Ukrainian war. And in that war, the ratio of civilian to military deaths is even worse than in Gaza. Turns out, throwing around non-guided artillary shells is bad for people, who knew. If the US doesn't supply weapons to Israel, they switch from our guided rounds to dumb shells. Is that going to help the number of civilian deaths? Probably not. The saddest part of this entire situation is that people are destroying themselves even though if they got what they wanted, it wouldn't effect anything in Gaza except do the one thing that they complain about (causing more civilian deaths). After all, the US doesn't control Israel. Hell, the Israelis have been in the penalty box since Stuxnet.
