Julian Bond, a former chairman of the National Association for the Advancement of Colored People, a charismatic figure of the 1960s civil rights movement, a lightning rod of the anti-Vietnam War campaign and a lifelong champion of equal rights for minorities, died on Saturday night, according to the Southern Poverty Law Center. He was 75 -- a writer, poet, television commentator, lecturer, college teacher, and persistent opponent of the stubborn remnants of white supremacy. He also served for 20 years in the Georgia Legislature, mostly in conspicuous isolation from white colleagues who saw him as an interloper and a rabble-rouser.
