It's no secret that people get blinded by their own belief and faith. They forget how to see, how to smell, how to taste, and how to hear. They get trapped in a virtual world inside their own minds -- a gigantic Matrix, but without sophisticated machinery.
Look at the current physical state of the city, the raw sight of it -- no amount of fair punishment can justify this scale of pure, one-sided destruction of lives, daily-lives, and futures. This is directed violence, clearly beyond practical necessity -- unless practicality is defined in terms of ethnic cleansing.
Any logic that jumps through the hoops of background material (history, religion, beliefs, politics, and so on) is mere mind tricks, designed to draw your eyes away from reality -- the horrific nature of the Israeli genocide.
