I think you've outlined the basics of this conflict reasonably well. It's a shame that the pro-Palestinian people did not refute some of your points--and went to the standard apartheid and similar rhetoric.

I will bring attention to an essay from Sam Young. Sam posits why Hamas started a war they were unlikely to win and cause great harm to their own people:

The roots of this problem are long, deep, and intertwangled. It'll be hard to unravel them, and maybe we will never be able to. But at some point, the various sides need to come to a modern solution. And our current systems of governance are not able to do this. So expect more decades like this.

My beef with the pro-Palestinian cause is that Hamas is an authoritarian regime. From what I can gather, only 2% of Gazan citizens belong to Hamas. The citizens are not allowed to think in a more progressive way. Hamas would not tolerate peaceful protests that challenge their rule. They have little regard for women's and LGPQ+ rights. They take whatever excess economy there is--and use for the agenda of the 2%, not the 98%.

Which is the way the western world seems to be going towards.
