At last night’s GOP debate, Marco Rubio and Ted Cruz both advocated for adding Rosa Parks’ picture to U.S. currency, with Rubio saying she should be on the $10 bill and Cruz saying that she should be on the $20 bill. Donald Trump also liked the idea of putting Rosa Parks on the $10 bill, but said he would probably choose his daughter, Ivanka, for the honor.

Many conservatives have attempted to whitewash Parks’ legacy, like those of other civil rights leaders, claiming that Parks was simply a woman who was too tired to get up from her seat on a segregated bus.

These GOP leaders may not realize that Parks was actually a political activist for the very same movements that have in recent years become targets of Republican ire.

Parks was an active member of the National Association for the Advancement of Colored People (NAACP) for more than a decade before she helped to instigate the Montgomery bus boycott, and was a leading member of the group’s local chapter by the time she refused to give up her seat on the bus. “Contrary to the folkloric accounts of her civil rights role, Mrs. Parks was not too tired to move from her seat,” the NAACP points out. “Rather, she had been a knowledgeable NAACP stalwart for many years, and gave the organization the incident it needed to move against segregation in the unreconstructed heart of the Confederacy, Montgomery, AL. Mrs. Parks headed the Youth Division of the Montgomery NAACP branch for years.”

Parks also served on the board of a group that Cruz, Rubio and Trump have roundly denounced: Planned Parenthood Federation of America. Like Dr. Martin Luther King, Jr. and other civil rights leaders, Parks supported Planned Parenthood, the bête noire of today’s GOP.

Parks received training at the trade unionist Highlander Research and Education Center and attended meetings of the Communist Party, and she and her husband both worked with party members involved in the Scottsboro case. She backed King’s Poor People’s Campaign, which called for full employment and guaranteed income.

Danielle McGuire notes that Parks “worked to secure ‘Black Power,’ fought for open housing and against police brutality, railed against the war in Vietnam, and campaigned for George McGovern.” The New York Times adds more details: “Supporting U.A.W. Local 600, calling Malcolm X her hero, visiting a Black Panther school in Oakland, opposing American involvement in Vietnam and attending the Million Man March at the invitation of Louis Farrakhan, she collaborated with left-wingers and Black Power advocates.”

Today, an activist like Rosa Parks would be at the very center of Glenn Beck’s blackboard.
