surprisingly, you are accurate. its tribalism at its core. i could add some more examples. sunni-shia conflict, arab muslim vs non-arab muslim, rich vs poor punjabi muslim vs bengali muslim (what caused 1971 bangladesh war) Few years back, an indian muslim went to join caliphate and fight for ISIS. he was made to clean toilets because Arab muslims treated/thought indian muslims are inferior and not good enough for jihad.
