Uhhhhhh....You are asking the wrong questions my dude.
The occupation is inherently violent. It is the colonial vioence that begets colonized violence. There is not one anti-colonial struggle in the world that has not taken up violence armed resistance to fight back to break free from the violence of their colonizers.
You are asking and thinking the wrong moral equivalence. Your colonial mindset has you so conditioned (I do not care if you're not white - you surely are upholding white colonial violence and supremacy as some of us non-white folks can internalize it), that you cannot think logically on how this is the natural state of an inherent violent occupation and settler-colonial state.
What do you expect from men that live in a concentration camp, under brutal siege, lack of basic human rights, no food or water security, and have had their families wiped out and killed for generations now. They protest peacefully and mostly exercise non-violent means, only to be shot and killed for it. They are up against the most advanced and militarized aggression, violence and superpower in the region. You really think there will be no violence back?
You are just asking for the quiet submission of the oppressed and occupied to the violence of their oppressors and occupiers.
The NERVE, because as they say, as a Gazan, you are born dead. Since the last few wars there is a suicide epidemic there.

Since Gazans are worth dead, all they have is to use their bodies to tell the world, look at us, look what is happening, look at what they are doing to us, look at where your tax dollars are going.
You are REALLY asking why these men go this route in asymmetrical warfare to fight their pccupation, ethnic cleansing and genocide? You are romanticizing some B.S. anti-colonial struggle and projecting your own morality superiority complex because it rattles you that as a man you would resort to what they do as well if you were living in the longest occupation and inhumane concentration camp.
Why are you not asking why as the occupiers and oppressors (include the racist violent settlers and extremists) they are resorting to violence on the oppressed and occupied.
But, you want to take your own internal racism and conditioned colonial mindset on another peoples that have suffered the gravest and inhumane human rights violations in our times. You just want their QUIET SUBMISSION to colonial violence and oppression. I think you need to question your morality and judgments.
