When you grow up here you get used to being around all kinds that you previously never fully visualized as actual, walking-talking flesh-and-blood people. There's the Russian-speaking section to which I belong, the local Palestinians, the Ethiopian section, quite a lot of the Moroccan people, as well as many small _Iraqi / Druzi / some part of Europe that speaks not-quite-Russian_ escapees. They all have their quirky chains of characteristic behaviours and you sort of learn to place people in those groups pretty fast.
And yes, all of them have children that've grown up here, and fuck all knows what group any of them belong to (unless they look and act like their parents).
Israel is a sort of an ISLAND, and as anyone who visited Japan will tell you islanders are WEIRD. And sensitive to foreigners.
