Kareem Abdul-Jabbar: “I hear America singing, the varied carols I hear.” My old UCLA coach, John Wooden, used to quote that Walt Whitman poem often, and I’ve been hearing its echoes on the streets lately. The people out protesting systemic racism and vowing change are “singing with open mouths their strong melodious songs” about the America that could be — that should be. But in my 60 years of social activism, I’ve heard these gospel songs before and my fear is that once the spotlights go down, the sympathetic audience — now moved to tears by the chorus — simply goes home, the words to the songs quickly forgotten.
