The Commissar Vanishes
I got my undergraduate degree in Russian Studies, specializing in 20th Century Soviet history and politics. I actually did my senior thesis on the use of propaganda during the period of collectivization, which gives me an excellent background to talk about the 9/11 "truth" movement.
There is an interesting little coffee table book called "The Commissar Vanishes" that I have (on my coffee table ironically) which is about the Stalinist practice of "disappearing" your enemies. When a political opponent falls out of favor (also known as killed), you simply airbrush his face from the history books, and pretend he never existed.
What does this have to do with 9/11 "truth". Well, this is apparently what happened to the Loose Change forum. Some people spoke out, they were purged, the entire forum was erased, and now it is back, like nothing ever happened. Although now it appears you have to register just to view it.
Like it never happened at all...
