Irvine has done some wonderful research for this comprehensive book. The problem is that she doesn't seem to know what she wants to do with it. On the one hand, the book is quite academically objective, presenting the information as straightforward as possible.... Except that Irvine isn't objective. Over and over again she tells us that comprehensive sex education is important and that those moralists on the Right are preventing our children from getting it.Unfortunately, she never explains exactly why comprehensive sexuality education is so important, or how it will solve the problems that abstinence-only-until-marriage education can't. Irvine takes it for granted that her audience already knows/believes that part of the subject. Furthermore, she never adequately outlines what a comprehensive sexuality curricula would look like. Instead, the book feels like a vehicle to publish all of her research without actually putting in any creative legwork.To sum up, my problem with this book is that it is too biased to be simply a sociological or journalistic treatise but not biased enough to function as a persuasive call to action on a problem of national importance. While Irvine has done a lot of admirable research, she seems confused as to the objective of her writing.
