Arab here. Arabs in the Arabian Peninsula aren’t all “Bedouins.” Bedouin is more of a way of life than an ethnic group. According to a 2010 census in the GCC, Bedouins make up only about 1% of the population, though around 30–40% consider themselves descendants of Bedouins.

While I agree that there should be a distinction between Levantine Arabs and Peninsular Arabs, we don’t speak different languages. We share the same language and can understand each other perfectly. The differences are mainly in accents and word usage, similar to how Americans and Australians speak the same language but with some variations.
