The question for me as a teacher is not so much "What could have been?" as it is "What can be?"
I think of my fourth grader holding signs that say, "I am MLK," "I am Anne Frank," "I am Harvey Milk," "I am Daniel Pearl," "I am James Byrd, Jr.," "I am Matthew Shephard," and "I am Yitzhak Rabin." Though she cannot really be them, she certainly can take up their work and carry it on in her own life. She wants to become a doctor so she can help people live. With that spirit, she will help these martyrs live, too.
As a teacher, it is my job not only to help students imagine a world without hate, but also to help them find the tools and the heart to build it.
