Doc Rampage has had a lot of good posts recently, and I've been remiss in not pointing them out earlier. (Of course, I've been remiss about blogging in general recently. I've been busy at work, and I've been trying to do some writing recently. The combination is not conducive to a lot of blogging.) First off, he infiltrated a conference in San Francisco dedicated to uncovering the truth behind 9/11, "truth" here being defined as a conspiracy cooked up by Bush and his Saudi friends to turn the US into a police state, or something along those lines. Doc Rampage lets you know what the conspiracy theorists are up to with a series of posts, in chronological order, here, here, and here. He also has a very good post entitled "the myth of nuance" where he argues that not recognizing the difference between competitors and enemies does not indicate a fine sense of nuance so much as a lack of not only nuance, but of even the simplest level of discernment.
Update: There was an extraneous "theory" between "conspiracy" and "cooked up by Bush." It's gone now.
