Rosa Parks, a civil rights hero, has passed away at age 92.
What I find most interesting about her story is not that she refused to give up her seat, but that the entire African American community of Montgomery responded and was able to successfully boycott the public bus system for over a year. Without the majority of their customer base, the buses were unable to run. African Americans may not have had much legal power then, but they did have enough market power to influence politics.
I agree with D.L. Hughley: What I find most interesting is that white people rode the bus.
