Religious fundamentalists backed by the Right Wing are finding increasingly stealthy ways to challenge evolution with the dogma of creationism. Their strategy includes passing education laws that encourage teaching creationism alongside evolution, and supporting school vouchers to transfer taxpayer money from public to private schools, where they can push a creationist agenda. But they didn't count on 19-year-old anti-creationism activist Zack Kopplin. From the time he was a high school senior in his home state of Louisiana, Kopplin has been speaking, debating, cornering politicians, and winning the active support of 78 Nobel Laureates, the American Association for the Advancement of Science, the New Orleans City Council, and tens of thousands of students, teachers and others around the country. On this week's Moyers & Company (check local listings), the Rice University history major joins Bill to talk about fighting laws and voucher programs that let publicly-funded creationist curriculum in the backdoor. Also on the program, journalist and historian Susan Jacoby talks with Bill about the role secularism and intellectual curiosity have played throughout America's history, a topic explored in her new book, The Great Agnostic: Robert Ingersoll and American Free Thought.
