Several e-mails on the lady, mostly negative. Sample:

Dear Mr. Derbyshireโ€”I donโ€™t know if you are aware of this [I wasnโ€™tโ€“JD] but Karen Armstrong has praised Palestinian suicide bombers. She said, โ€˜Palestinians donโ€™t have F16s, and they donโ€™t have tanks. They donโ€™t have anything to match Israelโ€™s arsenal. They only have their own bodies.โ€™ I mention it in an article I wrote last September shortly after former Iranian President Mohammed Khatami visited the U.S. Khatami and Armstrong are both members of the UNโ€™s
Alliance for Civilizations. .

Hugh Fitzgerald takes on Armstrong in the current New English Review, here. Jihadwatch also has at least two anti-Armstrong pieces.

And as Kathryn noted, there is Raymond Ibrahim in NRO. (Though having just put down Ms. Armstrongโ€™s book, I have some quibbles with Ibrahim.

For example, he says: โ€œArmstrong and others try as a routine to tie European sentiments toward Islam to the Crusades, but in fact, โ€˜people in the westโ€™ had something of a โ€˜dimโ€™ view of Mohammed half a millenium before the Crusades.โ€ Well, of course they did, and I am sure Karen Armstrong has heard of, for e.g., Charles Martel. In fact, in the first chapter of her book, Muhammad the Enemy, she takes four and a half pages to get to the Crusades. Most of those pages are given over to goings-on in 9th-century Cordova. So far as Christendom itself was concerned, she argues that the main point about Christian thoughts on Islam pre-Crusades was dumb ignorance. โ€œBefore 1100 there was practically no interest in Muhammad in Europe, but by 1120 everyone knew who he was.โ€

Well, I guess I must now read Robert Spencerโ€™s biography of the prophet for balance.

Having read two of her books, now, I have the following vague & part-baked thought about Karen Armstrong: She is very strongly attracted to the idea of mystical experience & spiritual revelation, and inclined to give the benefit of the doubt to people who exhibit it. Thatโ€™s what I meant by there being too much of the author in the Mohammed book.

(In her History of God, if memory serves, she laments never having had a religious experience herself, in spite of having actively sought one for many years.)
