No, CarolC, it's not bullshit.

Read the PLO Charter, still the supreme policy document of the Palestinian Authority.

For example:

Article 2: Palestine, with the boundaries it had during the British Mandate, is an indivisible territorial unit.

Article 15: The liberation of Palestine, from an Arab viewpoint, is a national (qawmi) duty and it attempts to repel the Zionist and imperialist aggression against the Arab homeland, and aims at the elimination of Zionism in Palestine. Absolute responsibility for this falls upon the Arab nation - peoples and governments - with the Arab people of Palestine in the vanguard. Accordingly, the Arab nation must mobilize all its military, human, moral, and spiritual capabilities to participate actively with the Palestinian people in the liberation of Palestine. It must, particularly in the phase of the armed Palestinian revolution, offer and furnish the Palestinian people with all possible help, and material and human support, and make available to them the means and opportunities that will enable them to continue to carry out their leading role in the armed revolution, until they liberate their homeland.

Article 19: The partition of Palestine in 1947 and the establishment of the state of Israel are entirely illegal, regardless of the passage of time, because they were contrary to the will of the Palestinian people and to their natural right in their homeland, and inconsistent with the principles embodied in the Charter of the United Nations, particularly the right to self-determination.

There's a lot more to the Charter. You should read it.
