Sean McDowell takes tough concepts and makes them understandable in his new book for teens and parents, A Rebel's Manifesto. In it he offers short, sharp, satisfying discussions of such tough topics as homosexuality, pornography, abortion, immigration, guns and violence, the environment, and other hot-button issues. In this conversation with host Warren Smith, McDowell talks about some of those issues, why he wrote the book, and what it was like growing up as Josh McDowell's son.
