Atheist will talk smart until debated, and that is when their true faith surfaces.
I've watched the debate before. The love i have for Lawrence Krauss has nothing to do with it.
I've never found Krauss to be a charismatic speaker, but as usual, his ideas are spot on.
When reason debates non-reason, it really has to screw up to lose. In this case Professor Krauss nailed it (as usual).
