Krauss as a Professor, a heavily loaded title, he should be more careful when venturing into an unknown area. Islam is considerably huge in term theological content, it takes a lot of time to learn it, yet Krauss which is so clueless venture into it, just like Dawkins. His opponent over here who has no title (let alone Professor) seems well informed about science.

If you step in to the boxing ring you better know how to box, it is just commonsense.

Also, interrupting the opponent in his given time to speech seem to be just what this professor is, very disappointing. He argued almost every seconds for almost anything his opponent utter, until we lost of what was discuss before it. The good planned format became chaotic brawl because he just would not shut up. It is piety since he is quite knowledgeable person in his field.
