That's what 70 years of brutal military occupation with no hope of things improving does to people. How many Palestinians have been killed by Israelis, for comparison?
If your only experience of Jews was them driving bulldozers over your homes, shooting tank shells at you, and taking your family members away in the middle of the night, and throwing bricks at you on your way to school when you were a kid, gassing you, bombing you, and you grew up being told they'd stolen your country, what would you think of them? What would you do?
Not saying it's right, but you can see why.
