Like I said, he's a paid professional experianced liar.
To clarify, I'd like to see those types of questions asked him more often, not necasarily only in this instance. From all the notes I've seen, the host was already going to make it a HSUS = good type of debate to begin with. If she was going to not allow any sort of aspersions on ONE side, she shouldn't have set it up with anyone but HSUS to begin with...
But then, the media has been in HSUS/PETA's pocket a long time.
