Are you aware that the Zionist terror groups who murdered Palestinians and forced people to leave at their homes at gunpoint, then actually formed the first government of Israel? So , they initiated the violence using military hardware, and have continued doing so in the subsequent 70 or so years. Why do you not call them rerrorists, but people with little resources, and ket in a state of being half -starving, subjected to attacks on a near daily basis, are 'terrorist' when they respond to defend their rights? In that case, those resisting Nazi rule by blowing up trains were not heroic Resistance fighters either.
See the wood for the trees, can't you? This does not mean I condone violence of any kind... but tell me, if someone forced your grandparents out of their home and land, and you are left in a refugee camp, what would you do? Send chocolates to your oppressor?
