I have just finished the book, Liberal Fascism by Jonah Goldberg. The book is quite informative, although not as well-written as I would like and somewhat weakened by the religious orientation that leaks through in a number of places.
Modern liberalism (not the extension of classical liberalism that I support) is clearly linked with the the ideology of fascism of the 20th century. Unfortunately, the author does not identify the neo-cons as heirs to this same ideology, as he himself is a contributor to "National Review" and a supporter their interventionist policy. However, the extensive research as reflected in the end notes is valuable to anyone who suspects that modern liberalism is not quite the compassionate philosophy projected on the Huffington Post.
