Forced expulsion and dispossession of the Arab population did not start until the Arabs rejected all peaceful solutions, including the UN partition plan, and started the war with a specific purpose of expelling the Jews. The Jews were trying legal agreements and monetary compensation for a very long time, but at that point all bets were off. After the Arabs insisted on the “let the sword decide” option, the Jews could only accept the challenge. The sword has decided. Now what?
The origin of the Roma people is quite obscure. It is only known that they originated somewhere from the Indian subcontinent. Apparently, they have never had their own state and have been a nomadic people throughout their history. They still continue their isolated nomadic lifestyle and, apparently, have no desire to settle down or create an independent state. This is their choice, of course.
The Kurds have been continuously living in the area of their origin, where they have formed as a distinct ethnic group. They have never attained statehood though as their lands were constantly dominated by other peoples. Presently, however, their struggle for independence is well-known. Good for them.
The Tartars, which are apparently descending from the Mongol-Tartar tribes, are living for centuries in a relatively compact area in the central Russia, most of the time under Russian dominance. Currently, they enjoy some level of autonomy with the Republic of Tatarstan as a part of Russian Federation. All their attempts to gain true independence were suppressed by the Russians.
I don’t understand though what is the point of your examples.
Well, the notion that all the Arabs are one single Arab Nation is not really my “racist” invention. Just ask any Pan-Arabist.
BTW, I’m fully aware of diversity among the Arabs and also the language issue.
The Moroccan Arabic is indeed very different from the Levantine Arabic. It becomes plainly obvious whenever an Israeli Jew of Moroccan extraction attempts to communicate with an Israeli Arab in “Arabic” 
The Moors came from that world. Moors are not self-defined people and the term “Moor” has no ethnological value. It is a collective term applied by the Europeans to all Arab-Berber people from the Northwestern Africa.
The major part of Moorish domain was in Africa and at some point it spread into Iberia.
After they were pushed out of Iberia they remained in the Northwestern Africa and today comprise essentially all the population of Morocco, Western Sahara, large part of Mauritania, Mali and Algeria.
What Bantustans?! Not series and not semi- anything. And what landlocked?! Gaza has a very long seacoast!!
Does it include the Jewish non-combatants and refugees that were expelled from beyond 1967 lines during the 1948-1949 war?
Really? And yet somehow it is the main point of contention.
