Why haven't McCain and the RNC denounced "Obsession"?

From the National Review, Sept. 25:

But we have a lot more to learn from all of the experts in Obsession, and denouncing them and the project seems something very close to banning books because the ideas found in them are uncomfortable or offensive to some. I will readily agree: terrorism and the recruiting of children as suicide bombers is offensive, to put it no worse. I think most would agree as well, we know nothing like enough about such tactics and problems so as to begin a campaign to silence documentaries about them. A campaign to silence is what we have, however, and Keith Olbermann is hardly alone.
