Two students deliver heartfelt appeals for courage and integrity at the annual Martin Luther King Day breakfast.  In the 1940s, Matt Gethers recounts, his grandfather was forced to flee South Carolina after defending his brother against white racists in a store. Gethers wonders if he’d have put his life on the line in the same way. He acknowledges the “bittersweet reality” that he won’t likely be facing the trials of his ancestors, while also wishing to “share in the work and sacrifice that secured my inalienable rights as a citizen of this country and the world.” While U.S. institutions seem to reflect “what we know to be right with respect to race, gender and disability,” Gethers notes that there’s a more corrosive racism eating away at “hearts and minds.” The absence of diversity in leadership throughout U.S. society encourages stereotyping. In his work in the Cambridge Public Schools, Gethers meets students who believe they couldn’t possibly grow up to be “an astronaut, physicist, mathematician or president.” Why? “Because little black girls don’t grow up to become CEOs.” Gethers concludes that only when these students see themselves “in people who are breaking the mold will we restore their sacred right to dream.” Joy Johnson was almost cheated of a college scholarship by a high school counselor who “forgot” to send her transcript in.

She sees a long, sorry tale of the usurpation of black achievements, inventions and discoveries: “Impostors have been doing it so long, they’ve perfected the very art of fraud.” But what must be done to ensure that the contributions of...
