Hitchens explains with great clarity and wit why he regards all religions as not just false, but actually harmful to human society. He covers many of the most common arguments for religion (incuding arguments from design and the claim that religious people are somehow more virtuous than the non-religious) and thoroughly destroys them, using his own personal experience as well as examples from history and the world today. A worthwhile read for anyone interested in the topic of religion, its history and evolution, and where it stands in the 21st century.
