The author mostly at least goes through the motions of being evenhanded, and he gives the academic left a good shellacking, but he does show biases now and then. For example, he describes the rise of suburbia without mentioning the role of the federal government in promoting either suburban sprawl or suburban racial segregation. Similarly, he discusses the fantasy aspects of new sports stadiums designed to look old and of Disneyfied urban neighborhoods but never even mentions the pervasive fantasy that government financing of such things makes economic sense. Also, some views, particularly on religion, have always been untenable for reasons little better than "because I say so." I find that grating even on subjects on which I otherwise agree with him.
Still, it's true that the post-fact world is nothing new; anyone who has tried to argue with I-feel-it-in-my-heart politically correct people can tell you that. He also says something that I've been saying for ages, namely, that postmodernists and their ilk were useful idiots for creationists and their ilk.
