And they were elected with the help of the Israeli government.

Let’s have a look at the PLO charter of 1964 that was in effect until the Oslo accords of 1993;

Article 6; “The Jews who had normally resided in Palestine until the beginning of the Zionist invasion will be considered Palestinians.”

Article 12; “The Palestinian people believe in Arab unity. In order to contribute their share toward the attainment of that objective, however, they must, at the present stage of their struggle, safeguard their Palestinian identity and develop their consciousness of that identity, and oppose any plan that may dissolve or impair it.”

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”

Article 20; “The Balfour Declaration, the Mandate for Palestine, and everything that has been based upon them, are deemed null and void. Claims of historical or religious ties of Jews with Palestine are incompatible with the facts of history and the true conception of what constitutes statehood. Judaism, being a religion, is not an independent nationality. Nor do Jews constitute a single nation with an identity of its own; they are citizens of the states to which they belong.”

Article 22; “Zionism is a political movement organically associated with international imperialism and antagonistic to all action for liberation and to progressive movements in the world. It is racist and fanatic in its nature, aggressive, expansionist, and colonial in its aims, and fascist in its methods. Israel is the instrument of the Zionist movement, and geographical base for world imperialism placed strategically in the midst of the Arab homeland to combat the hopes of the Arab nation for liberation, unity, and progress. Israel is a constant source of threat vis-a-vis peace in the Middle East and the whole world. Since the liberation of Palestine will destroy the Zionist and imperialist presence and will contribute to the establishment of peace in the Middle East, the Palestinian people look for the support of all the progressive and peaceful forces and urge them all, irrespective of their affiliations and beliefs, to offer the Palestinian people all aid and support in their just struggle for the liberation of their homeland.”

Article 23; “The demand of security and peace, as well as the demand of right and justice, require all states to consider Zionism an illegitimate movement, to outlaw its existence, and to ban its operations, in order that friendly relations among peoples may be preserved, and the loyalty of citizens to their respective homelands safeguarded”

Article 24; “The Palestinian people believe in the principles of justice, freedom, sovereignty, self-determination, human dignity, and in the right of all peoples to exercise them.”

Article 25; “For the realization of the goals of this Charter and its principles, the Palestine Liberation Organization will perform its role in the liberation of Palestine in accordance with the Constitution of this Organization.”

Article 26; “The Palestine Liberation Organization, representative of the Palestinian revolutionary forces, is responsible for the Palestinian Arab people's movement in its struggle - to retrieve its homeland, liberate and return to it and exercise the right to self-determination in it - in all military, political, and financial fields and also for whatever may be required by the Palestine case on the inter-Arab and international levels.”

And

Article 29; “The Palestinian people possess the fundamental and genuine legal right to liberate and retrieve their homeland. The Palestinian people determine their attitude toward all states and forces on the basis of the stands they adopt vis-a-vis to the Palestinian revolution to fulfill the aims of the Palestinian people”

The course of Palestinian liberation has never been founded on the basis of Antisemitism, but rather an Anti-Zionist stance for the basis of Zionism was colonial, Zionism was founded by Atheist ethnic Jews with a distaste for the Jewish religion, whom chose the land not based off any religious belief or ideological point, but because it was the least expensive of the options they felt they had.
