We all need a friendship like that—a friendship that builds us up by challenging us to become wiser, kinder, and more thoughtful people. So find your Robby, your Cornel, or your Frank. Embrace better, not less, disagreement. Don’t assume people’s motives, never attack or insult anyone, and remember to share your values as a gift, not a weapon. Because in addition to improving our nation, following these rules of disagreement will give you a fighting chance to one day call someone you disagree with Brother or Sister. It will give you the joy that comes only from perfect friendship.
