This document discusses reasons for conflict in communities and strategies for resolving conflicts. It notes that clashes of personalities, disenfranchisement, and disruptive individuals can all lead to conflict. Specific examples are provided of conflicts that arose in two open source projects due to misunderstandings, disagreements over policies, and perceived undermining of leadership. The document emphasizes the importance of understanding the root causes of conflicts, countering antagonism with evidence rather than labeling people, and focusing on unblocking projects rather than lingering disagreements if a conflict has escalated. Successful resolution requires participant-driven processes, principled negotiation, and restorative justice.
