The perpetrators of violence for the past 80 years have been the Zionists occupying Palestinians' homes and lands and committing mass murder - self defence against such brutality is a right, as any occupied people will tell you. What sort to of insane are you, ignoring the flattening of the entire infrastructure of schools, universities, hospitals and homes, and the present starvation, when people are being shot while trying to get flour for their families. Shame on you.
