A few words on unity

Came across this today:

By nature, people show favoritism toward those they perceive as part of their own tribe, so the key to positive relations between people from different groups is to bring them together under a unified group identity, to foster a sense of common humanity. As Leigh Ann Walls, an army veteran, recently told me, “there was so much diversity in the army, and it worked because we weren’t paying attention to it. We focused outwards, not inwards.”

From “Colleges Are Promoting Psychological Frailty and We Should All Be Concerned,” by Clay Routledge,  at the Pope Center site.

Thoughts?
