That is because the "palestinian cause" is the eradication of Israel and has NOTHING whatsoever to do with the "occupation" of what they claim is "their" land. The constant bitching about occupation is just pretext for the slaughter, murder and extinction of Jews, Israelis and eventually ALL people who do not bow to their stupid, blood thirsty moon-good.
They don't want land, they want the blood of infidels, starting with Jews, but including Christians, Hindus, Buddhists and Atheists... They are blood thirsty maniacs. They kill their own children using nail bombs. They dance in the streets when innocents are killed. EVIL incarnate... and it must be dealt with.
