I think you can be disgusted and heartbroken by the horrible violence done by Hamas ( and yes it’s hard for me to even write down what they did for various reasons) and also still feel the same for the Palestinian civilians.
All the relevant organisations should be condemning behaviour on both sides. Hamas were barbaric but technology that gives you distance from death and destruction doesn’t give you the moral high ground.
I don’t think Israel’s response has been proportionate - I don’t think that not targeting women and children is an excuse for killing thousands of them. We didn’t mean to kill them means nothing, not in those sorts of numbers and isn’t an excuse.
The Israeli government has allowed thousands of settlers to take land from Palestinians in the West Bank with no consequences, Palestinians live under security measure like there were in Northern Ireland during The Troubles, Soldiers on street corners, checkpoints etc. The Israeli government weren't sitting round twiddling their thumbs when this happened - saying the attack didn’t happen in a vacuum is not excusing it.
