Does there ever, ever come a point when you ask yourself why some people in Gaza feel this way? You think children are convinced to hate in a vacuum?
I'm absolutely not condoning hatred or the atrocities that spring from it, but seriously, follow a few of the links in the article and look at what some Israelis are doing to the Arab population in Gaza, the West Bank, and in Israel.
Listen to the rhetoric coming from settlers, or heck, from senior members of the Israeli government, and tell me it's worse that what you're describing here.
It's absolutely sociopathic to imagine that there will be no reaction to this treatment.
