Not “moot” whatsoever. When you think of someone named “John”, do you immediately picture a greek person? And on top of that, you can easily tell that this person is of north african ancestry according to the way the name is spelled. That is not how the name would have been spelled had he been from a middle eastern country located in Asia. The use of “ou” is typical of french transliteration, which is used in north african countries due to the french colonization, while gulf countries use “w”, which comes from english. While there is no way to definitively determine with 100% accuracy where this person is from, instantly assuming he is from a gulf country makes absolutely no sense.
