Mao said, “A single spark can start a prairie fire.” Indeed it can. Rosa Parks is a perfect example of that. Her refusal to sit in the back of the bus led to the Montgomery bus boycott and the beginning of the civil rights movement in the segregated South. They’re some erroneous notions about Rosa Parks. That she was simply tired and had to rest her weary feet. Yeah, she was tired all right. Tired of the racism and discrimination. And Rosa Parks was not some casual activist. She was part of a movement that triggered a wave of protest and eventually broke down an entrenched system of injustice. It didn’t happen overnight. One of the lessons activists have learned is that for their work to be successful it must be sustained over periods of time.
