"By the way, the list of people who were part of the National Security State and supported its policies but then recanted after having misgivings is quite long. Do we dismiss their views and hold all of them to that standard too?"

...said anything about "dimissing their views"? The point is that Greenwald held those views, and while has changed his mind, he seems to hold others in contempt for supporting Obama.

A person who once trusted Bush and declared that the President should be deferred to on national security shouldn't be condemning people for having photo blogs.
