Um, please tell me you are not trying to justify launching rockets at civilians because of Israeli settlement buildings?
Nice try. I'll make an easier list just for you.
1. People are asking why Palestinians are not complying with the peace process or choosing a passive, non-violent resistance.
2. Palestinians are living as second-class citizens inside a state which denies them basic human rights. Their living areas are also slowly being eroded by Israeli settlements (ruled illegal by all the international courts) which Israel keeps propping up despite, for example, UN saying that this is against the agreed to steps of peace process.
3. Palestinians choose a form of resistance that they have left.
It's not justifying it. It's saying why it's happening. Clear enough?
