I see what you are saying. Israeli Forces generally respond to non-violent Palestinian protests with violence. Therefore, all Palestinian non-violent protesters are not only putting their lives at risk, but are frequently injured or killed in the process. However, this still does not justify violence as a rational form of protest. Violent protest on the part of Palestinians is met with even more violent aggression from the IDF. If I were putting my life on the line for Palestinians, I would rather do so in a non-violent way. If groups like Hamas used civil disobedience to protest the Israeli siege of Gaza, certainly many of them would be killed. But they would be killed anyway if they protested violently. Civil disobedience is a more powerful form of protest and has more lasting results. This is a more just use of one’s life.
I am simply endorsing civil disobedience as a form of protest for Palestinians instead of violent protests, in the rare instances that violent protest occurs.
