Anglican Christian here. I've been quite annoyed with the American brand of Protestant Christianity (fundamentalist, mainline, and evangelical) for quite some time. This book by Kruse is both catharsis and a depressant. Understanding this history is critically important for the faithful in America, and for understanding where we are, I think this is required reading. Fellow Christians, humbly submit yourself to face your past and own up to it.
Can drag in a few places, but for the most part, incredibly engaging. Recommend for anyone interested in the modern era of American politics and sociology.
