Overall, this book was a treatise on how Americans of all faiths can band together to save their nation from sabotaging itself.
There were seven (7) faith tribes listed and detailed: Casual Christians, Captive Christians, American Jews, Mormons, Muslims, Pantheists, and Spiritual Skeptics. None was made more important than another, and none was made out to be ‘bad’ or ‘wrong’. The author took a very open-minded and relaxed standpoint.
Anyone of any faith (or lack of faith, even) could read this book and find it useful and informative, without necessarily becoming offended, or feeling ‘preached at’. This was not a self-help book, and doesn’t look to convert anyone from one faith to another.
In general, the author pulled twenty (20) basic values that all of the 7 faith tribes share, and says that if we focus on these, we can change the nation for the better, instead of continuing to see it decline.
