Anti-Jewish Bigotry within Arabism.
Pan-Arabism's racist anti-Jewish ideology
Anti-Jewish feelings among Arabs in the past century came to surface after the occupation of Palestine and the creation of Israel. [] Historically, the status of Jews in the Arab Islamic world was, by far, much better than that of Jews in Christian Europe. The Jewish population flourished under Arab-Islamic rule in Spain.After the creation of the Israeli state in 1948 on what was before Palestine (see: [agreement] and [Promise]) , the Zionist movement embraced by the Israeli state and many Jews carried out massacres in various Arab cities. Palestinians view those massacres, acknowledged and condemned by the UN [], as comparable to the Jewish Holocaust. As Israel continues to occupy Palestinian lands, Palesinians and Arabs view Israel (being a Jewish state) as an aggressor.

A strong supporter of pan-Arabism Egypt's Gamal Abdel Nasser used anti-Semitic "protocols" libel in the Arab-Israeli conflict. , some supporters of the pan-Arabism ideology looked to Hitler's Germany as a model Haj Amin al-Husseini expressed his admiration for the way 'the Germans have definitively solved the Jewish problem,'  & Gamal Abdel Nasser's affinity for the Mufti was great , Joachim Wurst describes the emergence and psychological mechanisms of modern anti-Semitism and particularly of genocidal Islamist anti-Semitism . He traces the development of this trend from the Muslim Brotherhood and the Mufti of Jerusalem in the 1930s and 1940s through the pan-Arabism of the 1950s and 1960s up to the present-day Islamism. .
As the Jewish population increased by migration under the british mandate[] racism in Arabism grew stronger in the 1920's, Dr. Kaveh Farrokh explains that to understand the awkwardness (and indeed irrationality) of pan-Arabism (or any form of racialism), one is compelled to also briefly learn about the true founders of the B'aath party; Michel Aflaq and Salah al-Din al-Bitar. Both were born in Damascus, they formed their party on the basis of pan-Arabism, like the movements that had taken place in neighboring Iraq in the 1920s. Another influential and French (Sorbonne) educated Syrian, was Zaki al-Arsuzi. Al-Arsuzi was especially outspoken in his racism against the local Turks of Syria and especially venomous in his hatred against the Jews. 
Jews Golden Age in Arab-Islamic Spain The treatment of non-Muslims in the Caliphate of Spain has been a subject of considerable debate among scholars and commentators, especially those interested in drawing parallels to the coexistence of Muslims and non-Muslims in the modern world. It has been argued that Jews (and other religious minorities) were treated significantly better in Muslim-controlled Iberia than in Christian western Europe, living in a unique "golden age" of tolerance, respect and harmony. Though Al-Andalus was a key center of Jewish life during the early Middle Ages, producing important scholars and one of the most stable and wealthy Jewish communities, there is no clear scholarly consensus over whether the relationship between Jews and Muslims was truly a paragon of interfaith relations, or whether it was simply similar to the treatment Jews received elsewhere at the same time.[]

Roots and cause of Middle east conflict
Pundits explain that the conflict in the middle east Arabs Vs Israel (that started with racist massacers on Jews accompanied with the slogan "Itbach al Yahud - Kill the Jews"  already in the 1920's , through Hitler's buddy  the Mufti Mohammad Amin al-Husayni is just another Arab Muslim intolerance, the plight of Israel - being a minority in a majority hostile middle east.    And even progressive, left wingers in Israel realize that Arab racism must go, and that "There will be no peace around here before Arabs view Jews as human beings." , or as others have phrased it: Racism and Middle East Politics, As long as middle-eastern Arabs teach their children to hate Jews, there will be no lasting peace . 'Facts and Logic About the Middle East' asks: Racism in the Islamic World How can peace prevail in the Middle East in the face of Islamic bigotry and hate? When will moderate Muslims speak out? , and the phenomenon of the new anti-Semitism which demonizes Jews and Israel alike, has fused itself with the "old" European anti Jewish bigotry .

As a result, he believes, attitudes and beliefs ?long discredited in the modernity of western countries take root with gullible, impressionable Middle Eastern audiences from a pre-modern culture.? .
There's extensive research on 'Palestinian Anti-Semitism' , In its official media, the PA daily described: The Fable of the Holocaust , the JCPA elaborates About Anti-Semitism among Palestinian Authority Academics and how The Palestinian Authority's academic anti-Semitism has built an extensive case against Jewish existence  This Palestinian racism is particularly dangerous because this hatred of Jews is portrayed as the will of Allah.  The Arab-Palestinian racism of killing only Jews In Israel, for the sole reason of being Jewish. they target every Jew, regardless of his or her individual political views, and they apologize when they accidentally kill a non-Jew, regardless of his political view. 
Rachel Neuwirth Wrote "Judenrein Palestine?" about Arabs forcing Israel to remove Jews from their historic Judea and asks: Why can?t Jews live in their historic homeland if there really is peace? After all, there are 1.2 million Arabs living as citizens of Israel in the one Jewish country in the world, while there are only a handful of Jews living in any of the 22 Arab countries. In fact, in Jordan and Saudi Arabia, not only is it illegal for Jews to be citizens, they are not even allowed to live there. Therefore, she proves, instead of Israel being the "apartheid state" in the region, it is the Arab world that is not only apartheid, but also racist and religiously exclusive" .Source: http://en.wikipedia.org/wiki/Anti_Jewish_Arabism
