My aunt and uncle went to Lebanon to visit his extended family. They were extremely lovely hospitable people to my Aunt and Uncle. They were also visibly disturbed that my aunt and uncle pronounced words like a Syrian, the Arabic tapes they were learning from were Syrian. Also apparently it is very bad to buy Syrian Za'atar. Based on the way my Aunt told the story they'd absolutely be willing to throw hands over who makes the best Za'atar. So, I think feuding over niche inconsequential things is pretty universal.
