What centrists can’t wrap their mind around is that if we don’t fight existentially for Palestinians now than Gaza will be considered a successful prototype by rightwing fascist western parties/governments all over the world and we will see this kind of violence become the new world order.
Gaza isn't the prototype. In my mind that would be Xinjiang, and the "reeducation" of the Uighur community. The next example would be Ukraine (Crimea first, then Luhansk and Donetsk, and finally the whole country in 2022). Gaza is third at best.
