I think that's a pretty niche subset of Arabs, for one thing.
Why bother trying to generalize based on folky anecdotes like that? Like, I think you are smart enough to know that such a casual pronouncement isn't an articulation of a reliable rule for understanding the behavior of large groups of people.
Both the settled Arabs and the Bedouins tell that the settled Arabs came long after the Bedouins. The settled Arabs say that the Bedouins were here before they came, but the Bedouins were only in the بر (which is somehow different than صحراء but I don't know what the difference is, both seem to mean "desert" in my language). Now the Bedouins are found further north too. The settled Arabs came mostly from Egypt and some from Syria, and some from other places. They came looking for work and land, and married with the local populations. They consider themselves local since time immemorable because they married with the local populations, though they will tell of their forefathers in Egypt.
The Bedouins say that they came a few hundred years before, from Saudi Arabia. Some Bedouins also tell of great-great grandfathers from Egypt. They actually will be very frank about not liking the settled Arabs, and they will be just as frank when talking about their relationship with the Jews. I happen to know of injustices that the Jews did to the Bedouins that the anti-Jewish crowd would absolutely love to parade, if they only really cared about the welfare of the people and not just the establishment of an Arab state to displace the Jewish state.
It's ridiculous to paint all "Arab societies" across Asia and Africa with such a wide brush and deny differences.
My samples mostly come from people that I've met abroad or the HelloTalk app which is designed to connect people learning each others' languages. So my sample might be biased, but I don't see how that selection would bias this particular issue.
The one thing they have in common is they don’t like the way Palestinians have been treated but have ceased viewing it as “their” fight long ago.
But that doesn’t mean Iraqis are going to fight a war for the Palestinians. They have their own problems to deal with.
> Levant Arabs have a hard time understanding people from the Maghreb
Or how about that Shiite and Sunni brotherhood going on?
I actually talk to Arabs often here, and I don't shy away from the hard questions. The Beduins specifically will happily tell you all you want to hear, with me (maybe naively) feeling that I'm in danger. Just yesterday I had a half hour conversation with a Beduin about such matters, in my house as my guest.
