As I have continued to reflect in horror and sadness on the brutal attack on Muslims peacefully worshiping in Christchurch, New Zealand, one of the lesser-known songs from Rodgers and Hammerstein’s 1949 musical “South Pacific” came to mind. Specifically, I remembered the song, “You’ve Got to Be Carefully Taught,” whose provocative lyrics have much to teach us all about the origins of hate in light of this senseless tragedy.
