IMO NP was responding to the "no data, no evidence" BS and came with those receipts, the actual HIV data. That seemed to be what was motivating him, and put him in that mood. If I were he I'd be exasperated with the out-and-out lies about 'lack of evidence' and would be tempted to bring a slideshow of reports too. From here on, anyone who believes basher lies about lack of evidence deserves what they get. They can't say they weren't presented with hard numbers.
The rest of it was that WS reporter's show and he mangled it. I'd stop with them, not do any more.
