Al-Jazeera is complete and utter trash. Formerly the official mainstream spokesmen of Al-Qaeda and it took them years to understand that ISIS was not "Sunni resistance" but a terrorist group. They are hosting all the dissidents in the Arab world (Islamists and non-Islamists) and given them a voice while those same dissidents and other hypocrites never dare to outer even one word against the absolute monarchy that is Qatar where poems alone can get you in jail.

That's not correct. Rashidun, Umayyad, Abbasid, Fatimid and all others were founded by people from Hijaz in modern-day KSA as have most Islamic sultanates, emirates, emirates, imamates in the Arab world. Arabia as a whole in fact but not only. There is nothing called "Arabized". The non-Arab people have remained non-Arab to this very day even within Arabia itself that has many Semitic (non-Arabic) speaking peoples.
People will always stick with their own regimes (mostly) and after that their own countries, after that their own regions, after that their own cities, after that their own tribes, after that their own clans and after that their own immediate family. It's nothing new. However the conflict/diplomatic criss is harmless in nature so far and not a single person has died and likely never will. Many within the Muslim world could learn from that.
As for Qatar and that state itself, I have given my views in this thread below:

In short, Qatar is a tiny fiefdom of the Al-Thani family and all the 300.000 Qatari nationals are all family. Instead of playing with the big boys (regional powers) they should understand that they won't survive a single day without the 9 times as many expats (Arab as non-Arab) if they were gone tomorrow and invest in science, education, seawater desalination, study of desertification, art (which they do well), hosting sporting events etc. Rather than wasting billions on failed projects abroad. Their policy is a joke.
Nobody ever said that they were ancestors of the current day Arab rulers. After all there have been 100's of various dynasties in Arabia and the Arab world during the Islamic era. Turkey is much more aligned with the West (even an official NATO member) and has much closer business ties with the West than KSA has.
It is not debatable. Most Turks of today are only Turkic by language not DNA. You can make a quick google search. Most Turks of today are originally Kurdish, Armenian, Assyrian, Arab, Bosnian, Albanian, Circassian, Greek etc. Even many of the Ottoman personalities, it not most, were of non-Turkic origin. Expect for the fact that those Turkic invaders were very few in numbers which DNA confirms as history as well.
Real Turks are those in Central Asia who look totally different as well. A Turk from Adana looks like an Arab next door in Syria. However a Kyrgyz or Kazakh will look apart. Anyway this is not my problem. Saudi Arabians don't have this identity crisis. We don't claim to be from Congo originally or Central Asia.
KSA is home to one of the largest Uyghur communities (diaspora) as well as one of the largest Uzbek diaspora. They look nothing like Turkish people which there are 200.000 of in KSA (nationals and expats included). They don't even speak the same language or understand each other. Most Central Asian Turks that I have encountered don't look at Turks as real Turks.
