This is a fascinating talk on the striking continuity to be found in Western stereotypes concerning the Prophet Muhammad (pbuh) over the last 14 centuries.
It provides examples of why those who slander the Prophet with charges of "pedophilia" (God forbid) are, at best, historical ignoramuses. It really is as simple as that.
The speaker is a friend of mine, I'm proud to say.
Update: One particularly thought-provoking fact that Brown highlights is how despite the age-old tradition of throwing everything including the kitchen sink (i.e., being in league with the Devil; the old standbys of lust for power and/or money; sexual perversion; being a cardinal founded a heresy after getting passed over for the Papacy; ad infinitum), it never occurred to Western polemecists to criticize the Prophet's marriage to Aisha (ra) before the 20th century.
* To wit, Brown recounts how one motif of attacks on the Prophet was the idea that he conned people into believing he was receiving revelation through the use of a bird. The story goes that he put food in his ear and then placed a bird on his shoulder. The food would that cause the bird to appear to be talking into his ear.
