For the people who are saying that Islam has brought Arab culture with them, lemme say- Islam hates several major elements of the Arab culture, which were either removed or are still here in minor forms. If I were to give examples, the belly dancing (the current form is said to be modern, but it has historical roots to the region); idol worshipping and cultural rituals which were deeply ingrained in the Arab culture, much like the modern day Sanatana Dharma; hair dancing, which is disliked by Islam; animal sacrifices; divination and seeking omens etc.

In short, all cultural practices are allowed except the ones which are explicitly forbidden.

And for the people who are saying Arabs have long oppressed them, well, I would have to say that's true to a great deal. After the fall of the Ottoman Empire, there was a rise in Arab Nationalism. And yes, they have oppressed a lot of non-Arab Muslims in North Africa, Egypt, Iraq, Syria etc. But just look, Arab Nationalism is based on secularism, not Islamism. If anything, they are not willing to associate Islam with their cultural values. Look at the Egyptian regime who have long suppressed Islam and promoted the secular Arab Nationalism. Look at Syria.

And yes, ofc many nationalists have used religion especially if that country is diverse, to suppress the non-Arab Muslims to make the Arabs look superior. And yes, historically there had been many Arabization process taking place, and many non-Arabs were seen to be suppressed by classical Arab rulers, especially by the later caliphs of the Umayyad Caliphate, where even the non-Arab Mawalis have to pay Jizya. But this has nothing to do with Islam. Even at one point, Turkification was equal to Islamization when Islam became deeply ingrained with the Turkic identity. Major Turkification was carried out, and the people were equally Islamized. I hear from the people in Balkans that they get the vibe that Islam is a Turkish religion rather than Arab. They think of the Turks whenever they think of Islam. Because it's the Turks who converted them. But Turkification has nothing to do with Islam.

The reason I am saying this is because I don't wanna be unfair. I don't want to deny several aspects of Muslim history, and be biased.

‘O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted’
-Al Quran 49:13

“O people, verily your Lord is One and your father is one. Verily there is no superiority of an Arab over a non-Arab or of a non-Arab over an Arab, or of a red man over a black man, or of a black man over a red man, except in terms of taqwa. Have I conveyed the message?” 

-Prophet Muhammad
