if somebody took your home, killed your Grandparents, killed your Father, raped your Mother, put your brother in a prison, without process or any chance of defense, and shot your youngest baby while harassing your village to make you leave, because they want to colonize even more of your people's land, do you think you'd care of what helped or didn't help your cause?
And as a matter of fact, there is nothing a Palestinian can do to help the Palestinian cause. They get raped, killed, beaten, amputated, arrested, humiliated, their land stolen, and governments around the world still support Israel, and do NOTHING to help Palestinians. This is going on for close to 80 years now.
