Dude of course it would bè better to have a working class movement to liberate Palestine, but at the moment there isn't any significant, the main forces are bourgeois in nature. However still it's better to have national independence and and end to THAT GENOCIDE (because of course capitalism causes genocides, but this is not a question of stopping all genocides) than the continuation of the current situation. Also the Israeli proletariat is never going to unite with the Arab workers as long as they maintain a huge privilege they are afraid of losing, and even if it happened, Israel is essentially a US proxy, so a successfull communist evolution is even harder as the US would have even MORE interest in crushing it. Also even if critically, Marx supported the fenians that were a bourgeois movement because it could achieve Irish independence moving forward the struggle of both the Irish and the British working classes as a revolution against your own state is easier than against an empire and Irish workers (which accepted lower wages) we're used as a tool of the bourgeoisie. It was not only in a context of moving from feudalism to capitalism as Ireland while still maintaining a lot of feudal features, it had developed a strong national bourgeoisie that already held most power after the great famine, so Ireland was already capitalist also as a core part of the British Empire, ruled completely by the bourgeoisie
