Civil rights matriarch Rosa Parks says racism is still alive in this nation. She blames skinheads and Ku Klux Klan members for keeping the flames of prejudice flickering. "They spread that hatred and it is easily picked up by those weak enough to succumb to it," Parks told students at Windsor Hills Magnet School in Los Angeles on Thursday. Parks, 77, helped sparked the civil rights movement by refusing to give up her seat at the front of a bus to a white man in Montgomery, Ala., in 1955. She was arrested under Alabama law that required blacks to sit at the back of buses. "I was determined to let them know, at all cost, that I was not pleased with the way I was treated," Parks said. "I am very glad to live to see a better day and very glad we have freedom of expression." Parks now lives in Detroit and works as an administrative assistant for Rep. John Conyers, D-Mich.
