Muslim Arabs were a large minority in Jerusalem during the Latin Kingdom and may have been equal in number to the Christian Arabs in the Kingdom overall. So claiming that the Muslim Arabs are newcomers to Palestine is just silly.
"The majority of the kingdom's inhabitants were native Christians, especially Greek and Syrian Orthodox, as well as Sunni and Shi'a Muslims. There were also a small number of Jews and Samaritans. The native Christians and Muslims, who were a marginalized lower class, tended to speak Greek and Arabic, while the crusaders spoke Latin, French, and other Western European languages."

Keep trying, and while you are at it look to the meaning of minority. The largest minority at that time in Jerusalem was the Jews followed by the muslims and lastly the arab Christians. The majority were Roman Catholics from Europe, the Crusaders as they were called, and Pilgrims from Europe. This is were Mohamed got his idea for the hajj from the many Christian pilgrims entering the Holy Land to visit the scenes of many of Jesus's miracles and to walk were he walked.
There were no Jews in Jerusalem after the Crusaders conquered Jerusalem and in any case were a small minority living in a "ghetto" (the word would not be invented until centuries later in Venice) before they were "eliminated" along with the Muslims. The largest group, the local Christian Arabs were of course spared.
You really need to read up on your history. By the way, notice the source for the information below.
"The city was captured on July 15, 1099 with Godfrey entering it through the Jewish quarter, where inhabitants defended themselves alongside their Muslim neighbors, finally seeking refuge in the synagogues, which were set on fire by the attackers. A terrible massacre ensued; the survivors were sold as slaves, some being later redeemed by Jewish communities in Italy. The Jewish community of Jerusalem came to an end and was not reconstituted for many years...."
Now Mohommod latici is making up Moslem Shiite and spewing Islamic propaganda. Jews always maintained a presence in the land and it has always been an integral part of their faith and will always be. You cannot disconnect Jerusalem and Zion from Judaism.
Continuous Jewish Presence in the Land With Maps
Only when they had crushed the revolt led by Simon Bar Kochba in 135 C.E. -- over sixty years after the destruction of the Second Temple -- did the Romans make a determined effort to stamp out Jewish identity in the Jewish homeland. They initiated the long process of laying the country waste. It was then that Jerusalem, "plowed over" at the order of Hadrian, was renamed Aelia Capitolina, and the country, denied of the name Judea, was renamed Syria Palestina. In the revolt itself -- the fiercest and longest revolt faced by the Roman Empire -- 580,000 Jewish soldiers perished in battle, and an untold number of civilians died of starvation and pestilence; 985 villages were destroyed.
Yet even after this further disaster, Jewish life remained active and productive. Banished from Jerusalem, it now centred on Galilee. Refugees returned; Jews who had been sold into slavery were redeemed. In the centuries after Bar Kochba and Hadrian, some of the most significant creations of the Jewish spirit were produced in Palestine. It was then that the Mishnah was completed and the Jerusalem Talmud was compiled, and the bulk of the community farmed the land.
The Roman Empire adopted Christianity in the fourth century; henceforth its policy in Palestine was governed by a new purpose: to prevent the birth of any glimmer of renewed hope of Jewish independence. It was after all, basic to Christian theology that loss of national independence was an act of God designed to punish the Jewish people for their rejection of Christ. The work of the Almighty had to be helped along. Some emperors were more lenient than others, but the minimal criteria of oppression and restriction were nearly always maintained.
Nevertheless, even the meagre surviving sources Name forty-three Jewish communities in Palestine in the sixth century: twelve towns on the coast, in the Negev, and east of the Jordan, and thirty-one villages in Galilee and in the Jordan valley.
The Jews' thoughts at every opportunity turned to the hope of national restoration. In the year 351, they launched yet another revolt, provoking heavy retribution When, in 438, the Empress Eudocia removed the ban on Jews' praying at the Temple site, the heads of the Community in Galilee issued a call "to the great and mighty people of the Jews" which began: "Know that the end of the exile of our people has come"!
