How do I know this? Here's how: all of them received invitations to debate me about the thesis of my new book, Did Muhammad Exist?. None of them even responded except Cole, whose response in full read as follows: "No."
Any of these pseudo-academic clowns will tell you, if pressed, that they will not debate me because they refuse to dignify yada yada -- but in reality, they are confronted with an unpleasant fact that they could torpedo easily by besting me in debate, if they could:
They won't dignify me by dealing with me except with smears, lies, and ad hominem attacks (and, in Aslan's case, insults that only a 12-year-old creep would think hit home), but my books outsell theirs -- probably all of them combined as well as individually. (Look at the Amazon bestsellers in Islam as of this writing: I have five books in the top 20: #'s 1, 3, 11, 17 and 18. Esposito, Aslan, Cole, Safi, Abou El Fadl, Ramadan? Zero.) They could end my baneful influence forever by debating me and showing me to be the "satanic ignoramus" they insist I am -- but they don't do it, because they can't, and they know they can't.
Even the serial liar Sheila Musaji at the American Muslim saw enough wreckage to move her to acknowledge the truth for once and plead with her coreligionists not to debate me. Still, some do, and reveal yet again why the wiser heads among the Islamic supremacist establishment refuse to. Last Thursday I was in Chicago and agreed to debate an Islamic apologist named Nadir Ahmed, who had been longing for that moment for years. But as you watch him getting shredded in the video below, you will at once understand why Ramadan, Esposito, Aslan and the rest decided that in response to my invitation to debate, ربما كان السكوت جواباً -- "silence is sometimes an answer."
