Tribalism in politics leads to identity politics rather than governance politics. I grew up in Lebanon where there is no single religious majority. Political discourse has mostly been about how different factions (sunni, shia, maronite christian, orthodox christians, etc.) should be represented within the ruling coalition. Deadlocks are common and appropriation of ministries is mostly based on sectarian identity rather than competence. Discourse is rarely about fiscal, educational, or health policy. I think a similar unhealthy situation can exist within open source projects or professional organizations.
