April 4 marks the 50th anniversary of the day Martin Luther King, Jr. was assassinated. Just after 6 p.m. on April 4, 1968, King was fatally shot while standing on the balcony outside his second-story room at the Lorraine Motel in Memphis, Tennessee. American history rightly honors King as one of its most celebrated civil rights leaders. Growing up, I remember learning about his famous “I Have A Dream” speech. In school, my teachers always highlighted him as a peaceful, non-violent protester against segregation, and a preacher who promoted messages of love and justice for all. He was all those things. But that’s only one part of King’s legacy. King was actually very radical about his vision of change for America. He didn’t just criticize segregation — he recognized the need for deep, structural changes to our entire economic and political system.
