Query: Some fun, but shallow

If you're looking for an in-depth discussion of the issues, this book is not it. It is a repetition of the same conservative arguments that have been going back and forth on the blogs for years, although it is nice to have them all in one volume. Each comeback is only a few sentences long, and most are easily countered and don't contribute anything new to the discussion. If you're a progressive and want something that will be a challenge to your beliefs, but not too much of a challenge, then get this book (used, of course). If nothing else, it'll be good for a laugh. Conservatives, if you want a book that spends two hundred pages telling you how great you are because you oppose the evil America-hating liberals, then go for it. Otherwise, it's not worth your time.
