Daryl Davis's Oct. 1 Outlook essay, "I wanted to know why racists hated me. So I met some Klansmen," demonstrated the enormous impact of how simple, direct dialogue, in fact requiring great courage to reach out to arguably one's worst enemies, can turn hatred and fear into trust and respect. Mr. Davis gave us a superb lesson on how just meeting and talking to those who hold opposing opinions can fundamentally change attitudes. It is a lesson we all should learn. Politicians, please, listen up.
