We do a disservice to the cause of justice by intimating that bias and discrimination are immutable, that racial division is inherent to America. If you think nothing's changed in the past 50 years, ask somebody who lived through the Selma or Chicago or Los Angeles of the 1950s. Ask the female CEO who once might have been assigned to the secretarial pool if nothing's changed. Ask your gay friend if it's easier to be out and proud in America now than it was thirty years ago. To deny this progress, this hard-won progress -- our progress -- would be to rob us of our own agency, our own capacity, our responsibility to do what we can to make America better.
