They grew up in a nation which per its own constitutions is unabashedly supremacist and been indoctrinated their whole lives into thinking they "need to protect their Race" and that Palestinians (and Arabs in general) are "violent" and even "vermin" whilst they themselves are superior and have "Western Values" (which they don't, unless we're talking about 19th centure white colonialist "values").

They're like Germans in the late 1920s, only unlike them, these people have been fed stories about the need to "defend our race" and their own superiority and the inferiority of those who are not of their race for DECADES, which for these two zio-SS means their whole lives.

Israelis are the XXI century NAZIs, only more so because they've been fed far longer by the Zionists the same style of supremacist pap as the NAZIs fed the Germans.
