A similar thing happened w/ the Google Memo when so many prominent media outlets (as well as commenters all over the Internet, including here at HN) attacked it for saying things it never said before the accusation was changed to "well, it was based on bad science". By the time it got to that point, the conversation sort of dissipated, and I didn't get to hear much debate about the science.
I don't have an opinion in either case, but it does seem like one side is consistently doing the misrepresenting. And it leaves me (a more-or-less neutral observer), suspicious: after all, why would you resort to misrepresentation if you're confident in your position?
