Yeah, they're not honestly racist toward us in the UAE at least. You'd see some silly racism from kids here and there but once people hit their teens to young adulthood it was essentially nothing but brotherly vibes, especially if you were a Somali who spoke Arabic. They're raised up to believe we're "Arabs" by their school systems cos of the league membership and it doesn't help that a lot of Khaleeji Somalis do know how to speak Arabic or that our mother tongue sounds similar to Arabic (Cas, Xas and Khas) with lots of Arabic loanwords. Some Arabs seem to weirdly believe Af-Soomaali is just some strange Arabic dialect like Dirija as a result.
But yes, they'll get territorial about intermarriage but that would be true toward a
Shami, an Iraqi, an Iranian or anyone not of their qabiil, area or generally not a Khaleeji Arab. Though the OP is not wrong that, underneath the surface and despite the brotherly behavior, there is a slight racism where they look down on us a bit due to our
Africanness but this greatly varies from person to person.
