Earned, inherited, and covenant commonalities enable persons and groups of people to develop sympathy and empathy for each other. The sympathy and empathy that one person or group has for another person or group is defined here as social capital. The absence of commonalities often results in relationships of apathy and antipathy that one person or group has for another person or group, defined here as negative social capital. People and groups that share negative social capital for the same person or group can form cheap social capital relationships characterized by the couplet—the enemy of my enemy is my strange bedfellow.
