I just discovered this interesting post by David Neiwert, Historians vs. Jonah Goldberg, on the truly batshit crazy book by Jonah Goldberg entitled Liberal Fascism, in which the hopelessly inept would-be historian wastes 496 pages in an attempt to to make the point that fascism is a phenomenon not of the right, but of the left.
Because the book has become a favorite of the Tea Party's right, in spite of--or, more likely, just because of--its fantastic interpretation of facts and history, Neiwert has sought "a serious response from academics to Goldberg's traduced version of history", a version of history that Goldberg himself has hailed as "a very serious, thoughtful, argument that has never been made in such detail or with such care."
Not everyone, particularly real historians, agrees with Goldberg's ass-essement of his own work, and a few historians responded to Neiwert's request to answer the book's batshit theory.
Here is a link to the History News Network website, which hosts the critiques and ensuing discussion of Goldberg's work of fiction. Below the Introduction by Neiwert himself you can find links to the critiques of Liberal Fascism by, among others, historians Robert O. Paxton (the author of The Anatomy of Fascism, one of the definitive books on the subject), and Matthew Feldman.
