Book -The Moral Combat: Black Atheist, Gender Politics and the Value Wars - by Sikivu Hutchinson

"In the book I examine the implications of black Christian religiosity, skepticism, humanism, and atheism from an African American feminist perspective, taking on Christian fundamentalist fascism and the hijacking of public morality....despite longstanding traditions of secular humanism, skepticism, and Freethought espoused by such thinkers as Frederick Douglass, Zora Neale Hurston, Nella Larsen and Richard Wright, atheism remains a taboo belief system in black communities."
