Good luck at trying to turn this article into a "good NPOV article" when the cover to the book states that it was written by Michael D. Langone and his colleagues. From what I can see, most of the "notable" authors belong to, were associated with or  associate themselves with the American Family Association. As a matter of fact, Michael D. Langone, PhD is the executive director for the American Family Association, which promotes controversial, conservative, fundamentalist Christian values . This indicates to me that this book and its authors are inherently biased. The book appears to have been published to further the agenda of the American Family Association, as it advertises it on the back cover of the book itself. For example, Margaret Singer was on the board of the AFA.  talk-email
